I was interested in future immersive display systems when I was a doctoral student, andthat’s why I was into optical MEMS. Due to the massive amount of data that needs to beprocessed in the display system, I thought it should be a self-assembled form of identicalactive display components that should organize itself as a display panel later. I proposed‘smart scalable systems' as a research theme that could enable such a massive system indisplay, energy, and biochips based on self-assembly of many heterogeneous 5.components.
Though the immersive display by self-assembly is still just an idea, this concept of smart
scalable systems evolved into multiple biotech innovations for the past 15 years in myresearch group. I will present the concept of smart scalable systems first. Then I will talkabout our researches in structural colored microparticles, DNA laser printer, life-saving
antibiotic test, laser-based single-cell genomics, a few of which already become commercial
products. It is even more interesting Iam applying again the technique I learned from theseresearches back to displays that use self-assembly. Life is a journey full of expectations andsurprises.
The use of synchrotron radiation by a great variety of fields has increased steadily worldwide forthe past decades. This, to a large extent, is a result of the availability of the much brighter thirdgeneration light sources, which allowed the development of new experimental techniques.
Recently, new advances in accelerator technology are opening up the possibility of even brighter
sources, which are being named fourth-generation light sources. Brazil gave an important
contribution to science in Latin America through the development of the necessary technology andthe construction of its first synchrotron between 1987 and 1997. Even though it was a secondgeneration machine, it was fundamental to develop the know how to build and operate asynchrotron facility as well as a significant user community. Moreover, its pioneering activities insynchrotron science gave rise, with time, to the Brazilian Center for Research in Energy andMaterials (CNPEM). CNPEM is a research center that combines the development and operation ofopen, multi-user, globally competitive laboratory infrastructures with integrated research anddevelopment in strategic areas, with focus on nanotechnology, biosciences, biotechnology, and biorenewables, cutting-edge engineering, and scientific instrumentation. Among these facilities,
Sirius, the new Brazilian synchrotron, stands out. It is a state-of-the-art light source, one of the first
fourth-generation machines in the world. It provides cutting edge research tools that will benefit awide range of areas, significantly increasing the capabilities of the Brazilian science.

Coffee BreakWe are now experiencing a revolution in optical technologies: in the past the state of the art
in the field of photonics transitioned from individual miniaturized optical devices to massive
optical circuits on a microelectronic chip that can be modified on demand. This revolution is

Solar energy is becoming increasingly important as a clean and renewable energy source.
One type of collector, the Direct Absorption Solar Collector (DASC), is a cost-effective andsimple design without the need for solar tracker elements. The use of nanoparticles in the
DASC has improved its performance, but challenges remain, such as high costs and handlingissues. In this presentation, we propose new designs for the DASC and Concentrating Solar
Thermal collectors based on waveguide mechanism, aiming to integrate them with building
structures. These designs use advanced algorithms to optimize performance and reduce costs.
We prototype the designs using Transparent/Clear 3D Printing and validate their efficiency

We report on post-processing experiments using hollow-core
photonic crystal fibers. We show that, by simultaneously
heating and internally pressurizing the fibers, we can taper ormodify the sizes of the fiber microstructure features.
Particularly, by employing a technique for selectively
obstructing the microstructure elements, we could attaintailored modifications of the fiber architecture, namely the
inflation of selected cladding tubes, which can be of interestfor the development of new devices and sensors.

We present an investigation of a hetero-core fiber optic

ends, forming a Multimode / No-core fiber / Multimode(MNM) structure, where the NCF fiber is the sensing part ofthe structure. The simple and low cost interrogation scheme
uses a laser and a photodetector. The sensor is able tomeasure refractive index variations with a resolution of

Sensing modalities and instrumentation for target detection and raging applications havereceived tremendous attention over the past decade. This has been driven in no small part by
the unsatiable demand for cheaper, more compact and significantly improved Light
Detection and Ranging (LiDAR), which is essential for autonomous navigation. The
detection of objects in the presence of significant background noise is a problem offundamental interest in sensing. In this talk I aim to demonstrate theoretically andexperimentally how one can exploit non-classical light generated in monolithic
semiconductor light sources in conjunction with non-local effects to enhance theperformance of optical target detection and model LiDAR system. Our protocols utilize
quantum time-correlation which are obtained from a spontaneous parametric downconversion sources. The protocols only require time-resolved photon-counting detection,
which is phase-insensitive and therefore suitable for practical target detection. As arepresentative comparison to such a detection protocol, we also consider a classical phaseinsensitive target detection protocol based on intensity detection. Unlike classical target
detection and ranging protocols, the probe photons in our detection protocol are completely
indistinguishable from the background noise and therefore useful for covert ranging
applications. The experimental results agree very well with the theoretical prediction. In
particular, we find that in a high-level environment noise and loss, our detection protocol canachieve performance comparable to that of the classical protocol that is practical in the
optical regime.
Amorphous oxides are prevalent in photonic technologies. They are transparent from thenear ultraviolet to the midinfrared and offer a large refractive index contrast with substrates
like Si which is exploited to confine light. In this talk I will describe how the optical andstructural properties of amorphous oxide thin films deposited by sputtering are tailored toengineer multilayer dielectric stacks with selected optical response for their applications tolaser science and photonics

I will discuss diffractive optical networks designed by deep learning to all-optically
implement various complex functions as the input light diffracts through spatially-engineered

imaging and seeing through diffusers, also enabling task-specific camera designs and new
optical components for spatial, spectral and temporal beam shaping and spatially-controlled

Quantitative biospeckle measurements in tomatoes atdifferent ripening stages are reported. The biological activity
was calculated with a correlation method using few seconds
videos recorded with a low-cost, lensless webcam. 543 and633 nm lasers were used as light sources similar orcomplementary to the tomato color. The webcam captures
videos at different angles, close or away from the quasispecular reflection. A new metric (ratio of the biospeckle
activity at two wavelengths) was proposed, allowing fordifferentiating biological samples at different stages.

During the Covid-19 pandemic, the rapid and accurate pathogen
detection has become increasingly important inpreventing/mitigating future pandemics. Photonic biosensors
have the potential to detect a variety of pathogens, with highsensitivity. Bimodal waveguides are among the most sensitive
photonic sensors demonstrated. However, they generally requirecomplex waveguide structures putting strain on fabrication. This
study investigates an interferometric sensor that exploits thefundamental modes at orthogonal polarizations, thus allowing for
the use of a standard silicon nitride rib waveguides. Simulation
results using COMSOL Multiphysics indicate over 60%
improvement in bulk sensitivity, relative to previously
demonstrated bimodal waveguides.

The world is experiencing a second quantum revolution, with the introduction of emerging
technologies based on generalizations of information science using principles of quantum
physics. Concepts such as interference, indistinguishability, uncertainty, and quantum
entanglement provide additional resources for processing, storing, and transmitting
information, as well as allowing more sensitive measurements of physical quantities. In São
Paulo, Brazil, and Latin America, we have important groups conducting academic researchin this area but relatively few efforts to transform this knowledge into technologies. We will
present proposals to change this situation, pointing out some sectors in which we can beespecially competitive in the development of emerging quantum technologies.
I will present some of our recent results on scanning based hyperspectral imagers, as well as
miniaturized spectrometers and spectral imaging system based on emerging subwavelength
structures. Combining with some advanced reconstructive algorithms, miniaturized spectral
imaging based on subwavelength filter arrays, tunable filters and co-modulated filter arrays
is promising for e.g. portable consumer electronics and wearable devices.

Artificial intelligence is transforming photonic networks, making them more efficient,reliable, and intelligent. It plays a crucial role in automation, design, resource optimization,and data analysis, enabling better service delivery at lower cost. Several lines of AI are usedin the areas of photonic networks, such as Machine Learning, which allows systems to learn
from data, restoring signal shapes, finding better routes, or anticipating failures without being
explicitly programmed; and intelligent metaheuristics, which are used to solve complex
optimization and search problems, allowing efficient solutions to be found in
multidimensional search spaces, such as network optimization, resource allocation anddevice design.
The increase in capacity provided by coupled space division multiplexing (SDM) systems isfundamentally limited by mode-dependent gain (MDG) and amplified spontaneous emission(ASE) noise. Therefore, monitoring MDG and optical signal-to-noise ratio (SNR) is essential
for accurate performance evaluation and troubleshooting. Recent works show that theconventional MDG estimation method based on the transfer matrix of multiple-input
multiple-output (MIMO) equalizers optimizing the minimum mean square error (MMSE)
underestimates the actual value at low SNRs. Besides, estimating the optical SNR itself is
not a trivial task in SDM systems, as MDG strongly influences the electrical SNR after theequalizer. In a recent work we propose an MDG and SNR estimation method using artificial
neural networks (ANNs). The proposed ANN-based method processes features extracted at
the receiver after digital signal processing (DSP). In this paper, we discuss the ANN-based
method in detail, and validate it in an experimental 73-km 3-mode transmission link with
controlled MDG and SNR. After validation, we apply the method in a case study consistingof an experimental long-haul 6-mode link. The results show that the ANN estimates both
MDG and SNR with high accuracy, outperforming conventional methods.
In order to satisfy the demand of Internet connectivity, the optical communications systems
industry urge for high-capacity and cost-effective solutions over a wide range of applications
such as submarine, terrestrial long-haul, metro and access networks, for traditional telecom
services providers (TSP), and data center interconnect (DCI), for cloud services providers(CSP). In this way, the coherent line interfaces continue to evolve the transmission rate per
wavelength from 100 Gb/s to 800 Gb/s in commercial systems. To support the growing
traffic demands, the next frontier in coherent technology pushes the single wavelength
capacity towards 1 Tb/s. To achieve a high transmission rate per wavelength as 1 Tb/s, themain physical degrees of freedom to explore in a coherent optical transceiver are the numberof optical subcarriers, modulation format, and symbol rate. Regarding the first, single-carrier
approaches come up as an attractive solution compared with multi-carrier implementations
due to the reduced transceiver complexity and cost. Specifically for a single-carrier solution,
the combination of high-order quadrature amplitude modulation (QAM) format, as the dualpolarization (DP) 16QAM in contrast with DP-64QAM, and high baud rate, currently, is thebest option to scale the bit rate of a coherent line interface, yielding to a reasonable trade-off
between implementation cost and system performance. Nevertheless, optical systems basedon high-order QAM modulation and high symbol rate are highly impacted by optical fiber
nonlinear distortions, noise sources and transceiver impairments such as linear and nonlinear
distortions of electrical and optical components. Now, efforts are made to mitigate nonlinear
effects imposed by the optical fiber and also distortions imposed by the transmitter andreceiver and, among them, the deep learning equalization has been a promising solution. In
this seminar, we present and evaluate an alternative receiver (Rx)-based deep cascadeforward neural network (CDNN) for transceiver impairments compensation applied to 1 Tb/s
coherent optical systems. Also, we describe the future works in order to implement a deeplearning equalizer for coupled transceiver-fiber nonlinearity mitigation and to define theoptimum neural architecture.

Elastic optical networks (EONs) have emerged in the past decade to promote efficiency inthe use of the fiber optical spectrum by a heterogeneous dynamic traffic. For this purpose, it
allocates to each user only the number of spectrum slots it needs to meet its bitrate anddistance requirements, so the allocated slots reach an efficiency close to the Shannon limit.
However, the heterogeneity and dynamicity of the demand produce long-living spectral
voids that degrade the spectral efficiency, so the non-allocated slots may stay deadlocked fora long time. In order to address this problem, machine learning may be used in order toestimate, in real-time, the profile of the demand for connections given by the sizes of therequests and their rates of arrival. With this knowledge, we have already shown, in a paper
published in 2022, that both first-fit and exact-fit algorithms may be outperformed in a single
link by a new algorithm that is aware of the sizes that may be requested by the traffic. We are
currently extending this capability by expanding the traffic-awareness to include theknowledge of the rates of request of each connection size. Preliminary results of thisapproach will be shown in the presentation, assuming adjacent assignments. The results
confirm the expectation of strongly enhanced reduction of fragmentation losses in many
instances, but not all. We expect to obtain more consistent results by combining the newalgorithm with the previous one.
Lightpath establishments and releases in Elastic Optical Networks generate fragments ofavailable slots that whenever the size of these fragments are inferior to the number ofrequested slots path-request blockings occur. To mitigate such undesired effect, an efficient
spectrum assignment heuristic known as Min Slot-Continuity Capacity Loss (MSCL) was
proposed. MSCL receives the slot-availability vector of routes potentially affected by theestablishment of a request and calculates the reduction in assignment capacity that would
occur if a specific group of contiguous slots were chosen to attend the request. This isperformed for each route and the group of slots that provides the lowest loss of capacity is
chosen. MSCL is shown in the literature to be very efficient, but is computationallyintensive. We present two classifier models based on deep neural networks to speed up the
MSCL spectrum assignment operation. The first decides between the use of First-Fit or
MSCL heuristic, with the aim of avoiding unnecessary MSCL calls whenever the applicationof First-Fit would provide the same minimum loss of capacity as MSCL. The second adds
the capability of pointing out the correct portion of the spectrum MSCL should look forwhenever First-Fit is not selected. Compared to the MSCL, simulation results demonstrate
great reductions on the execution time of the two proposed models without compromising
blocking performance.
Federated Learning (FL) enables distributed machine learning while preserving user privacyby training local models using private datasets and sharing only model parameters with acentral server. However, FL imposes specific latency and bandwidth requirements, requiring
efficient resource allocation in the communication network. This work introduces two novel
Dynamic Wavelength and Bandwidth Allocation (DWBA) algorithms for Time andwavelength Division Multiplexing Passive Optical Networks (TWDM-PONs). The firstalgorithm employs bandwidth reservation, while the second utilizes statistical multiplexing
to ensure Quality of Service (QoS) provisioning for FL traffic over 50 Gb/s Ethernet PON
networks (50-EPON). These algorithms improve the TWDM-PON operations by effectively
allocating resources for FL processing while preserving QoS for other network traffic. This
contribution facilitates the practical deployment of FL in PON environments by addressing
the network requirements of FL operations without compromising the QoS demands ofdelay-critical applications.

Thin-film lithium niobate (TFLN) is a promising candidate
for photonic-based quantum information technology. This
platform combines large nonlinear and electro-opticalcoefficients with the tight confinement and reduced footprint
characteristic of integrated devices. Nonetheless, current
high-performance devices in TFLN generally rely on the useof hydrogen-silsesquioxane (HSQ) resist, or on silicon
dioxide hardmasks, adding complexity to the fabrication
process. Here, we fabricate and characterize opticalresonators in TFLN using readily available organic deep UV

In this talk we will discuss recent advances in wafer-scale
integration of Micro-Electro-Mechanical Systems in astandardized Silicon Photonics platform. Our highperformance Silicon Photonic MEMS tuneable couplers,filters, switches, and phase shifters, provide an advanced
technology basis for emerging applications requiring verylarge-scale photonic integration. We will outline theassembly approach for interfacing with optical fibres andintegration with control electronics to enable programmable
photonic integrated circuits.
We study the edge states that emerge in a system composed of a
topological photonic crystal and a trivial one. We verify the
emergence of the edge modes and we investigate their main features.
Our numerical results show that they are pseudospin modes and they
are well localized at the interface between both photonic crystals.
Furthermore, the robustness is studied by adding defects at theinterface. We verify that the defects have mild effects on thetransmission of the light along the system. We conclude that the edge
modes are protected by topology and robust against disorders anddefects.

The paper presents some results of the noise spectralinterferometry (SI) for precise distance measurement in subTHz Infra-Red and optical radiations using low-coherence
optical sources beyond their coherence zone. It is shown thatwhen the path difference of arms in Michelsoninterferometer exceeds the coherence length of the lightemitting diode radiation, the interference pattern in spectral
domain enables to perform absolute measurements of microand nano- distances due to its dependence on both time delay
and relative phase of the signals. Application of SI for
coherent imaging in X-ray is briefly discussed“Applications of Spectral

We present a sensing device that combines plasmonic Au
nanodiscs with dielectric layers. The sensor is operated in
Kretschmann configuration and delivers highly complex andsensitive reflectance curves as a result of hybridized
plasmons and Fresnel reflections from the microfluidic
device in which the plasmonic chip is embedded. Using
multivariate analysis for analyzing multiple features of thereflectance curves in angular interrogation, strongly helps
improve the sensing performance in comparison with astandard sensing chip of a continuous Au thin film. We
improve analytical sensitivity, sensor resolution, andprediction errors by 200%, 23%, and 38% respectively.
A subwavelength perforated structure designed for a
maximum absorption-to-mass ratio has been utilized toconstruct an uncooled infrared (λ~8-12 µm) thermal detector
operating in the air with a noise equivalent temperature
difference (NETD) of 23 mK and detectivity of 1.1×10^(9)cmHz^(0.5)/W while time constant is 1.5 ms. With a fill
factor of ~27%, the detector shows an average absorption perunit mass of ~6.8×10^(12) kg^(-1) over the long-wave
infrared regime. Mach-Zehnder interferometry has been used
for the optical readout of the detector.

Silicon nitride has emerged as a promising material forphotonic integrated circuits. To design and optimize futuresilicon-nitride-based optomechanical devices, it is essential
to fully understand the photoelastic tensor. We use microgear

optical spectroscopy we characterize the optical response of
the devices made in the silicon nitride foundry. As a future
step, we will characterize the optomechanical coupling of thedevice. By comparing the experimental results withsimulations, we aim to fully characterize the photoelastic

The evolution of optical networks, with a focus on
supporting next-generation connectivity solutions, is driving
the development of technological solutions aimed at
reducing capital and operational expenditures and energy
consumption while increasing capacity, reach, andinformation security in optical transmissions. Within thiscontext, this paper addresses recent developments and trends
in coherent systems, optical amplification, integrated
photonics, software-defined networking, and the use ofquantum-based cryptography, which are highlighted acrossvarious scenarios, including transport, data centerinterconnects, access, and mobile xHaul.
In this paper, we propose and evaluate a scheme to enhance
the performance of optical networks using routesegmentation (RS) limited to modulation format maximum
range. We have performed this study with an incremental
traffic model considering the densely-connected CORONET
topology taking the C-band and C+L-bands, with andwithout the adoption of fiber augmentation (FA). The results
show that this strategy can be an interesting way to improve
network performance regarding blocking and bit rates.

To verify and validate the use of machine learningtechniques for chromatic dispersion compensation, wedeveloped an end-to-end recurrent neural network (RNN) to
replace the digital signal processing (DSP) blocks used in
optical transmission and reception. We also evaluated thesensitivity of the developed networks to certain
hyperparameters. Our analysis indicated that the number ofneurons and the number of epochs were the most impactfulparameters, and we also observed that using lower values forthese parameters resulted in performance that was closer tothat of a conventional DSP implementation.

The impact of noise in the pump profile of distributed
Raman amplifier (DRA) for extended bandwidthtransmissions is investigated. Specifically, a continuous
pump generated by a shaped amplified spontaneous emission
signal is employed to fit the DRA gain profile to apredefined target. The analysis is performed by comparing
the power profiles obtained by the artificial neural networks(ANN) and by conventional numerical models for the Raman
amplification process, resulting in errors below 0.5 dB.
