CRC Press Advances in Photonic Crystals and Devices

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. About the Author Narendra Kumar was born in 1976 in Pitro, a village located in Bhojpur district of Bihar, India. He received B.Sc. (Hons.) and M.Sc. degrees in Physics from Banaras Hindu University in 1996 and 1998, respectively. Prior to graduation, he completed his schooling from PTPS (Patratu) High School and St. Columba’s College, Hazaribag, Jharkhand. He obtained a doctorate in Applied Physics from IIT-BHU in 2002. During his doctoral research, he worked on the propagation characteristics of some optical waveguides with new smart structures as well as one-dimensional photonic crystals. Dr. Kumar is an Assistant Professor (in senior grade) in the Department of Physics, School of Sciences, Mody University of Science and Technology, Lakshmangarh, Sikar, Rajasthan, India. He has over 16 years of experience in academics and research. His research interests include Optoelectronics and Photonics. He has published more than 24 research papers in the peer-reviewed international journals and presented papers in several national and international conferences. He has also co-authored 4 book chapters in the books published from globally recognized publishers. Some of his works have been extensively cited by many leading researchers in the field. His three books have been published by major abroad publishers including Nova Science Publishers, Inc. (USA). He is a member of Board of Studies at Mody University and has designed several curricula in Physics for UG and PG levels. He has supervised five master-degree dissertations and co-supervised four doctoral theses. He has also served as Head, Department of Science, during 2013–2015 and thereafter as Coordinator, Department of Physics, for 3 years at Mody University. Dr. Kumar is in the editorial board of the International Journal of Electromagnetics and Applications (SAP), USA, and associated with some international journals as an invited reviewer in his area of expertise. He is a Life Fellow of Optical Society of India and the Indian Science Congress Association. Bhuvneshwer Suthar was born in 1983 in Bikaner, India.
