This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multibeam interference lithography is investigated as a manufacturing technique for three-dimensional photonic crystal templates. In this research, optimization of the optical setup and the photoresist initiation system leads to a significant improvement of the optical quality of the crystal, as characterized by normal incidence optical spectroscopy. Theoretical spectra are calculated and demonstrate close agreement with experimental values, indicating that this fabrication process achieves excellent optical quality. X-ray microscopy provides non-destructive inspection of the fabricated crystals at nano-scale resolution. A reconstructed crystal model is generated by computed tomography which allows for comparison to a predicted structure's geometry and optical spectra. Using the polymer crystal as a template, electrodeposition is performed to completely infiltrate the crystal with Cu2O. After polymer removal the inverted Cu2O crystal exhibits a high peak reflectance at the predicted wavelength, indicating the structure is an exact inverse of the template. A conformal growth algorithm is developed for the commonly used chemical vapor deposition infiltration technique to explain growth results and verified experimentally with atomic layer deposition of oxide materials. Finally, a customized chemically amplified positive photoresist system and its processing steps are developed as a route to zero-shrinkage template material for high fidelity patterning of the designed interference patterns.

This book was released on 2008 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonic crystals are widely recognized for their light extraction properties paving a way for extensive use in optical communication and many other fields where there is a need for manipulation and control of light and its properties. Though one dimensional photonic crystal in the form of diffraction gratings and two dimensional photonic crystals are widely used in various optics applications, recent work in three dimensional photonic crystals is allowing their use as thermal emitters. Previous work done on three dimensional photonic crystals with various fabrication techniques have enabled thermal emission but beyond the visible wavelength region. The basis of this thesis dissertation is to lay the foundation for the use of photonic crystals as Thermal emitters within the visible wavelength region leading to enhanced emission which could in the future be an ideal replacement for other optical sources. This work presents the Design, simulation and Physical characterization of Tungsten photonic crystal filaments for enhanced black body emission. The major focus area is the simulation of the Crystal structure using the software FDTD Solutions to obtain the accurate dimensions for the fabrication of the structure. The initial steps of the fabrication process were then carried out with emphasis on Thermocompression bonding to obtain the first layer of the woodpile structure. Several strength measurements were carried out to emphasize the Bond strength characterization and the first layer of the overall structure was successfully obtained. The crux of this work is mainly simulation and Initial fabrication process mainly comprising of Thermocompression bonding and characterization following the bonding.

This book was released on 2018 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examine a multilayered one-dimensional (1D) polarizing photonic crystal designed and fabricated out of a single material. This polarizer is designed for high reflection of the s polarization and low reflection of p polarization at the wavelength of 632.8 nm. This device is fabricated implementing the oblique angle deposition technique to produce six-bilayers of alternating high to low indices of titanium dioxide using e-beam PVD for depositing on top of a fused silica substrate. For modeling, we used transfer-matrix method and numerical finite-difference time-domain analysis to simulate behavior of the 1D photonic bandgap structure. Both model and simulation predict better than 98% reflection for s polarization and less than 1% reflection for p polarization at wavelength of 632.8 nm at an incident angle of 70°. The fabricated device exhibited 94% reflection for s polarization and less than 6% reflection for p polarization at 632.8 nm at an incident angle of 70°. The results are in good agreement with theoretical predictions.

Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, there has been a phenomenal growth in the field of photonic crystal research and has emerged as an interdisciplinary area. Photonic crystals are usually nanostructured electromagnetic media consisting of periodic variation of dielectric constant, which prohibit certain electromagnetic wave frequency ranges called photonic bandgaps to propagate through them. Photonic crystals elicited numerous interesting features by unprecedented control of light and their exploitation is a promising tool in nanophotonics and designing optical components. The book ‘Advances in Photonic Crystals and Devices’ is designed with 15 chapters with introductory as well as research and application based contents. It covers the following highlighted features: Basics of photonic crystals and photonic crystal fibers Different theoretical as well as experimental approaches Current research advances from around the globe Nonlinear optics and super-continuum generation in photonic crystal fibers Magnetized cold plasma photonic crystals Liquid crystal defect embedded with graphene layers Biophysics and biomedical applications as optical sensors Two-dimensional photonic crystal demultiplexer Optical logic gates using photonic crystals A large number of references The goal of this book is to draw the background in understanding, fabrication and characterization of photonic crystals using a variety of materials and their applications in design of several optical devices. Though the book is useful as a reference for the researchers working in the area of photonics, optical computing and fabrication of nanophotonic devices, it is intended for the beginners like students pursuing their masters’ degree in photonics.

This book was released on 2010 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonic crystals are artificially engineered structures designed to prohibit light propagation in pre-defined spectral intervals called photonic bandgaps by creating regular distribution of the dielectric constant in one, two, or three dimensions, with a period of the order of the pertinent light wavelength. Among many techniques used for preparation of 3-dimensional photonic crystals, colloidal crystallization is arguably the simplest method allowing the fabrication of well-ordered large-scale lattices from colloidal nano-particles. The aim of this project is to extend functionalities of 3-dimensional colloidal photonic crystals for moulding and trapping light by introducing hetero-interfaces and transforming the crystal surface in order to control the in- and out-coupling of the light in the photonic crystal. Specifically, the main accomplishments are: i), the design, fabrication and characterization of novel metal-dielectric hybrid photonic crystals, the metal surface of which supports the Surface Plasmon Polaritons in the spectral range overlapping the photonic bandgap structure. This approach has brought the uniquely broad optical functionality of hybrid nanoarchitectures that rely on synergy of three independently tuneable resonance phenomena, namely, the photonic band gap, the extraordinary transmission and the microcavity resonance in contrast to solely diffraction in parent photonic crystals. ii), the design and fabrication of heterogeneous photonic crystals by integrating the self- and force-assembled (Langmuir Blodgett technique) colloidal crystals of different topologies. The mismatch of the light modes in such hetero-crystals results in the controllable light scattering and guiding at the hetero-interface. The broadband and omnidirectional light trapping was achieved by adding a metal layer at the hetero-interface. Such interface light trapping is a new prospective approach to photon management for the next generation of photovoltaic cells and superbright light sources.
