abstract: Abstract. Internet based communication has become a major field, with a user base that is expanding day by day. The needs have overloaded the available bandwidth, and higher speed has become a mandatory requirement to satisfy the user demands and increased use of the internet. Therefore, there is a need for high performance computers due to increasing dependence on computing technology. Optics is emerging as the best possible solution over electronics because it is capable of providing parallel data processing with fewer expenses and greater speed of more than 10,000 times faster than electronic computers. The main building block of optical computing is the all optical logic gates, which are designed using different techniques. Different types of photonic crystal based all optical logic gates have been reviewed in detail by discussing the key characteristics and demonstrating the advantages over the previously available technologies (semiconductor optical amplifier and nonlinear waveguide) that are used to build all optical logic gates.

abstract: Abstract Optical modulation technique plays a crucial role in photonics technologies, and there is an ever increasing demand for broadband and ultrafast optical modulation in the era of artificial intelligence. All optical modulation is known to be able to operate in an ultrafast way and has a broadband response, showing great potential in applications for ultrafast information processing and photonic computing. Two dimensional (2D) materials with exotic optoelectronic properties bring tremendous new opportunities for all optical modulators with excellent performance, which have attracted lots of attention recently. In this review, we cover the state of art all optical modulation based on 2D materials, including graphene, transitional metal dichalcogenides, phosphorus, and other novel 2D materials. We present the operations mechanism of different types of all optical modulators with various configurations, such as fiber integrated and free space ones. We also discuss the challenges and opportunities faced by all optical modulation, as well as offer some future perspectives for the development of all optical modulation based on 2D materials.

abstract: The ability to process optical signals without passing into the electrical domain has always attracted the attention of the research community. Processing photons by photons unfolds new scenarios, in principle allowing for unseen signal processing and computing capabilities. Optical computation can be seen as a large scientific field in which researchers operate, trying to find solutions to their specific needs by different approaches; although the challenges can be substantially different, they are typically addressed using knowledge and technological platforms that are shared across the whole field. This significant know how can also benefit other scientific communities, providing lateral solutions to their problems, as well as leading to novel applications. The aim of this Roadmap is to provide a broad view of the state of the art in this lively scientific research field and to discuss the advances required to tackle emerging challenges, thanks to contributions authored by experts affiliated to both academic institutions and high tech industries. The Roadmap is organized so as to put side by side contributions on different aspects of optical processing, aiming to enhance the cross contamination of ideas between scientists working in three different fields of photonics: optical gates and logical units, high bit rate signal processing and optical quantum computing. The ultimate intent of this paper is to provide guidance for young scientists as well as providing research funding institutions and stake holders with a comprehensive overview of perspectives and opportunities offered by this research field.

abstract: We review our recent results on the linear optical sampling (LOS) enabled all optical modulation format analyzer. Precise characterizations of arbitrary 128 Gbps PDM QPSK wavelength channel from 1550 nm to 1570 nm are successfully achieved, when a 101.3 MHz frequency spaced comb with 3 dB spectral power ripple of 20 nm is used.

abstract: Abstract The rapid growth of packet based Internet traffic and big data, associated with interconnected Data Centers (DC) and High Performance Computing (HPC) systems have imposed the need for ultrahigh link capacities and ultrahigh packet switching speeds, at network nodes. In order to overcome these ultrahigh demands, and particularly packet routing and forwarding, All Optical Label Swapping (AOLS) has been considered for many years as an established solution. This survey paper gives an updated and thorough investigation on AOLS technology and trends, based on a vast reference amount of research milestones throughout all this long time era. All types of labeling techniques are presented and compared, and their pros and cons are summarized all together. Moreover, important issues and directions for research are discussed, giving researchers guidelines and motivation for extended investigation.

abstract: The all optical encoder (AOE) based on photonic crystals (Ph.Cs. is one of the most important devices in computing systems. The essential related parameters are the delay time, the switching speed and the contrast ratio (CR) Moreover, the design simplicity, the compact size and the multi wavelength operation have come as a fabrication and functional relevant attributes. Throughout the upcoming lines, an introduction for the important assessment factors and definitions will be presented. Finite difference time domain (FDTD) and plane wave expansion (PWE) methods were used for analyzing all structures. An intensive overview of the photonic crystals (AOE) was achieved for the recently published (4x2) and (8x3) types. The corresponding functional parameters for each design were explored, and comparison tables were organized. Finally, numerical methods were discussed with the accompanying commercial software packages; then a future view for the higher performance operation was attained.
