Photonic crystal devices are capable of controlling the flow of light in ultra compact scales. Silicon two dimensional (2D) nanostructures are well developed in the integrated circuit (IC) industry. Silicon is transparent to infrared light and has high refractive index which makes silicon an ideal material for photonic crystals in the infrared spectrum. Silicon 2D photonic crystals have attracted a lot of interest for showing feasibility of photonic integrated circuits. Typical photonic crystal devices are waveguides or cavities, which were developed as mostly passive devices. Various methods can be used to make photonic crystals tunable. In this work, silicon 2D tunable photonic crystal devices are studied using thermo-optic effect of silicon. In addition, this research presents one-step lithography to form micro and nano combined structures for the two-dimensional slab photonic crystals.

Photonic crystal devices have been extensively researched in the past two decades due to its ability to generate and manipulate the electromagnetic waves in compact scales. Numerous non-conventional optical phenomena such as negative refraction, super lensing, superprism, sharp bending of light with low loss, and slow light were demonstrated due to their unique photonic band structures. However, most of the devices are passive devices without any means of external control. Since the photonic band structure is closely related to the refractive index of its composing material and lattice structure, modulation of the refractive index through thermo-optic effect or modification of the lattice structures by mechanical stretching would lead to change of the photonic band structure and result in active tuning of the photonic crystals. This work is a study on the Micro-Electro-Mechanical Systems (MEMS) based tunable photonic crystals as MEMS is ideally positioned to be integrated with photonic crystal to locally provide needed external excitation.

The majority of the contributions in this topically edited book stems from the priority program SPP 1113 "Photonische Kristalle" run by the Deutsche Forschungsgemeinschaft (DFG), resulting in a survey of the current state of photonic crystal research in Germany. The first part of the book describes methods for the theoretical analysis of their optical properties as well as the results. The main part is dedicated to the fabrication, characterization and modeling of two- and three-dimensional photonic crystals, while the final section presents a wide spectrum of applications: gas sensors, micro-lasers, and photonic crystal fibers. Illustrated in full color, this book is not only of interest to advanced students and researchers in physics, electrical engineering, and material science, but also to company R&D departments involved in photonic crystal-related technological developments.

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 discusses design, modeling, and the characterization of slow-light photonic crystal waveguides. Guidelines are developed to obtain slow-light waveguides with broadband characteristics and with low disorder-induced losses. Three functional devices are proposed and studied: A tunable dispersion compensator, a tunable optical delay line, and a high-speed electro-optic modulator. Optical and microwave measurements confirm the designs.

Liquid crystal (LC) etalon and photonic devices are explored for applications in high tunability wavelength select switches and display devices. A new approach to polarization independent LC etalon with twisted LC structure is proposed for applications in portable projection displays and a demo device exhibiting high transmittance, and millisecond switching speed is presented. In addition, designs for LC etalon based switchable mirror with 30 nm spectrum bandwidth and high tunability 1D photonic-crystal are numerically demonstrated.

Photonic crystals are periodically structured electromagnetic media, possessing photonic band gaps, (ie: ranges of frequency in which light cannot propagate through the structure). In this publication, the authors present current research in the study of the technology, theory and challenges of photonic crystals. Topics include photonic crystal tunable filters driven by an electrical control signal; recent patents on tunable photonic crystals; diamond photonics; design of high performance tunable reflectors by using 1D ternary photonic band gap structures; photonic crystal fibre non-linear characterisation and application to generate multi-wavelength brillouin fiber lasers; and a new multilayer structure for temperature stable performance in infrared optical filtering.
