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.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The computer revolution experienced in recent years has been possible thanks to semiconductor materials, such as silicon, germanium and gallium arsenide. The success of the silicon-based microelectronics is due to the ability to integrate multiple elements on the same chip such as processors, memories, and interfaces. However, the increasing miniaturization and the realization of faster devices have revealed the difficulty to overcome the intrinsic limits of these materials. For example, devices have to dissipate the heat produced by the enormous power density involved, without damaging themselves , and the lengths can not be reduced indefinitely if one wants to ensure the synchronization of the signals. All these limitations have led to research into technologies that overcome the physical limits of the silicon-based microelectronics. From the outset, the most promising approach has been photonics. In photonics, the so-called photonic crystals have aroused a widespread interest. These innovative materials are fundamental for the construction of optical circuits, i.e. circuits in which the transmission of information is carried out by photons instead of electrons. These materials can be considered as the optical analogue of semiconductors: in semiconductors the presence of a periodic potential, causes the formation of electronic energy bands separated by forbidden intervals called energy gaps, where there are not electronic states. In a photonic crystal, a periodic distribution of dielectrics with different refractive index causes the formation of a so-called photonic energy gap: photons with energy values internal to the forbidden gap can not pass through the crystal and will be refected or conffined inside of it. The goal of this thesis is the fabrication of photonic crystals based on macroporous silicon technology and their optical characterization using infrared spectroscopy in order to reveal the presence of photonic band gaps. All the fabrication and characterization processes were carried out in the clean room and laboratories of the "Universitat Politècnica de Catalunya (UPC)" , thanks to the collaboration of the "Grup de Recerca en Micro i Nanotecnologies". The thesis is structured as follows: in Chapter 1 are presented the theoretical aspects related to photonic crystals, as well as the mechanism of formation of macropores in n-type silicon wafers by electrochemical etching. In chapter 2 is explained the fabrication process of the macroporous silicon photonic crystals detailing all the process steps to which the silicon wafer is subjected to obtain the desired structures. Photographs taken by a scanning electron microscope (SEM) are also reported to verify the correspondence between the obtained structures and those drawn in the design phase. In Chapter 3, using the MIT photonic band gap (MPB) software package, developed by the Massachusetts Institute of Technology (MIT) , the band diagrams of different photonic structures are computed to study how certain design parameters could affect the position and width of the photonic band gaps. Chapter 4 presents the results of the refection and thermal emission measurements, carried out by Fourier Transform Infrared spectroscopy (FT-IR) to determine the optical response and to verify the presence of photonic band gaps in the fabricated structures. Finally, in Chapter 5 are given the conclusions of this thesis.

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.

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.
