This book highlights the guiding mechanisms as well as the most current and important results in the field of innovative, bio-inspired Bragg fibers. While conventional optical fibers (COF) have several advantages over traditional waveguides, they also suffer from a number of disadvantages which are not present in Bragg fibers due to their minimal nonlinearities, lack of polarization or birefringence effect, lack of Fresnel reflections at the open fiber end, and absence of material or cladding losses. A natural platform for biological and chemical sensing, and with potential to boost communication systems'' speed and bandwidth, the primary goal of this book is to apprise readers in academia and industry of properties of EM wave propagation in Bragg fibers with a defect layer. Their major applications in bio/chemical sensing, fuel adulteration sensing, high-temperature sensing, optical dual-channel inline filtering, optical de-multiplexers, optical couplers, and nonlinear soliton generation are presented in detail, along with comparisons of Bragg fibers with alternative structures and their relative pros and cons.

The book presents the collated and high-quality proceedings of the Conference on Recent Technologies in Electronics and Photonics held during 9-10 February 2024 at MIT-WPU, Pune, India. The main objective of this book is the introduction of recent innovations and current trends of photonics and electronics along with advanced device applications. Photonics and electronics together are shaping up to be the two main pillars of innovation for sustainable development and technological advances. The emphasis in this book will be on presenting recent application-based research in the mentioned fields rather than purely theoretical ideas.  The readers will gain insights on recent innovations across many fields of photonics on one hand: laser science and nonlinear optics, photonic materials, nanophotonics, solar photovoltaics, optoelectronics, green photonics, and fiber optics and a diverse set of topics in electronics on the other: Semiconductor Electronics, Electronic Materials, Microelectronics, AI/ML, Internet of Things etc. The book is useful for early career researchers in Science and Engineering, as also university professors and industry professionals.

This book highlights recent advances of optical spatial solitons in photorefractive materials ranging broadly from the coupling, modulation instability, effect of pyroelectricity, and the stability of photorefractive solitons, among other topics. Photorefractive solitons have been at the forefront of research because of their formation at low laser powers and unique saturable nonlinearity present in photorefractive materials which supports solitons in (2+1) D. There has been a spurt in research on photorefractive solitons recently, which has contributed to a greater understanding of the theoretical foundation of photorefractive solitons as also of their various interesting and practical applications. The book elucidates the diversity of photorefractive solitons and provides a good resource for students, researchers, and professionals in the area of nonlinear optics.
