abstract: Meet us at Photonics West 2019 South Hall Booth 343 A diffractive optical element (DOE) uses thin micro structure patterns to alter the phase of the light that is propagated through it. Those micro structures, once properly designed, can manipulate the light to almost any desired intensity profile or shape. This technology enables many functions and light manipulations which are not feasible with standard refractive optics. In many applications, these functions are highly beneficial and improve system performance significantly. Diffractive optical solutions have many advantages such as: high efficiency, high precision, small dimensions, low weight, and, most importantly, are flexible solutions that meet a variety of different applications' requirements.

abstract: In the past few decades, the advancements in nanotechnology have significantly altered many fields of science and technology, especially electronics and integrated photonics. Free space optics, on the other hand, has remained mostly unaffected, and even today "optics" reminds us of carefully shaped and polished pieces of various types of glasses and crystals lumped into lenses and beam shapers. Several of these devices are then combined into more complicated optical systems like microscopes and pulse shapers that are expensive, bulky, sensitive to various environmental factors, and require several alignment steps. This thesis contains my work on designing and utilizing structures engineered at the nano scale, which are called metasurfaces, to implement compact optical elements and systems with capabilities beyond those of conventional refractive and diffractive optics. My contributions to this field are two fold: I have developed and contributed to the development of new concepts that take metasurfaces beyond conventional difractive optics in various aspects, in addition to paradigm changing platforms for optical element and system design. Here, I first give an overview and a brief history about optical metasurfaces. Next I discuss the unprecedented capabilities of metasurfaces in controlling light based on its degrees of freedom like illumination angle and polarization. Then, I will focus on various novel metasurface platforms of conformal and tunable metasurfaces, 3D metasurface beam shapers, and integrated metasurfaces. I conclude with an outlook on future potentials and challenges that need to be overcome for realizing their wide spread applications.

abstract: Abstract. An innovative type of optical component a volume Bragg grating has recently become available commercially and has found wide applications in optics and photonics due to its unusually fine spectral and angular filtering capability. Reflecting volume Bragg gratings, with the grating period gradually changing along the beam propagation direction (chirped Bragg gratings CBGs) provide stretching and recompression of ultrashort laser pulses. CBGs, being monolithic, are robust devices that have a footprint three orders of magnitude smaller than that of a conventional Treacy compressor. CBGs recorded in photo thermo refractive glass can be used in the spectral range from 0.8 to 2.5 mm with the diffraction efficiency exceeding 90% and provide stretching up to 1 ns and compression down to 200 fs for pulses with energies and average powers exceeding 1 mJ and 250 W, respectively, while keeping the recompressed beam quality M2<1.4, and possibly as low as 1.1. This paper discusses fundamentals of stretching and compression by CBGs, the main parameters of the gratings including the CBG effects on the laser beam quality, and currently achievable CBG specifications.

abstract: Controlling the flow of light is one of the major challenges in modern optics. With optical telecommunication and computing technologies becoming increasingly important, there is an ever growing need for devices that will be able to control and manipulate lightwave signals. Guiding of light over large distances with ultralow losses has revolutionized the communications industry, allowing for fiber optic transmission of information. Therefore, it is certainly conceivable that the control of light flow on a microscopic scale may equally well open a new era in the realms of computation, quantum electronics, photonics, optical chips, and functional devices. Classic means for controlling light signals are Bragg mirrors, waveguides, resonators, and beam splitters. However, considering that the diversity of modern optical devices has dramatically increased, there is now a plethora of new challenges in our quest for new ways of controlling light. An example of desired lightwave based functionality is optically switchable windows, whose appearance can be switched on demand (e.g. from opaque to totally transparent and vice versa) It is thus clear that such sorts of applications fundamentally entail an exploration and pursuit of new ideas, designs, and photonic devices that will enable us to mould the flow of light beyond current constraints. Photonic crystals (PCs) are engineered structures that have a photonic functionality on the materials level, enabling the complete prohibition or allowance of the propagation of light in certain directions and at certain frequencies. They accomplish this feat by means of a periodic modulation of the refractive index of a suitable host medium. Within these three dimensionally periodic structures, the distribution of electromagnetic modes and their accompanying dispersion relations differ dramatically from those of bulk media. PCs are, in this regard, highly attractive because they allow the design and manipulation of their photonic properties based on a so called aband structure engineering.a In particular, it swiftly turns out from a pertinent modal analysis that PCs possess photonic band gap (PBG) regions, i.e. regions in which the propagation of photons is forbidden and the density of allowed electromagnetic states vanishes. These regions can be designed to exist in one two or three dimensional structures, depending on whether the dielectric constant is periodic along one direction and homogeneous in the others (1D PCs) periodic in a plane and homogeneous in the third direction (2D PCs) or periodic in all three directions (3D PCs) Although 1D PCs have been known and well studied for decades in the form of highly reflecting dielectric (Bragg) mirrors, the idea of constructing a 2 or 3D PC is no more than about two decades old. From the start, 3D PCs have attracted enormous attention by scientists, owing to the prediction that they posses highly unusual features, such as full 3D PBGs, and also because of the conceivable applications of these structures. Some of the best known 3D PCs are the Yablonovite structure, the alayer by layera structure, the silicon woodpile structure, and the opal and inverse opal PC structures.

abstract: Recent experimental and theoretical results have shown that crossing a probe laser in a plasma with a secondary pump can modify the amplitude, phase, and polarization of the probe in a controlled manner. Beyond fundamental physics, these results suggest that a pump plasma based optical system could be used to amplify and control a laser pulse at high power, where the high fluence precludes using an optical system. This paper attempts to clarify the transient regime of such a pump probe plasma system. An analytical solution is derived to the coupled equations in the relevant regime, valid for any frequency detuning, coupling strength, and damping. Asymptotic expressions in the scantly studied off resonance regime are derived. The time to reach the steady state is found to be roughly independent of the detuning. This time to steady state defines the response time of such a plasma photonics system and can be made potentially much faster than traditional optics by controlling the damping of plasma acoustic waves. We comment on the steady state assumption typically used to interpret current experiments and design future ones.

abstract: Summary form only given. Inertial Confinement Fusion (ICF) experiments at the National Ignition Facility (NIF) have unveiled a wealth of new insights into the physics of laser plasma interaction (LPI) in the presence of many laser beams. Besides their crucial impact on ICF experiments, these findings have also revealed new ways in which LPI processes can alter the fundamental optical properties of plasmas (optical anisotropy, refractive index modifications, dispersion etc. These findings have led to the proposal of new ideas to manipulate light using plasmas, including conceptual designs for new plasma based optical systems such as plasma polarizers, wave plates and dielectric mirrors. Compared to traditional (crystal based) optics systems, such plasma based photonics devices essentially alleviate the constraints of optics damage, and can manipulate laser beams at fluences millions of times above the damage threshold of solid state optics. In this presentation, some of the main recent findings on multi beams LPI in NIF experiments will be reviewed, as well as how their analysis has led us to pursue new research in "plasma photonics" Recent and on going experiments at the Jupiter Laser Facility (LLNL) to test and validate these new schemes will also be presented. A tunable plasma waveplate was recently demonstrated (D. Turnbull et al. submitted) and was used to produce near ideal circular polarization of an intense laser beam. Follow up experiments aimed at demonstrating a plasma based polarizer and dielectric mirror are currently in preparation.
