Studies on Band Structures and Electromagnetic Density of Modes in One Dimensional Photonic Crystals Perturbed by Acoustic Waves

Abstract

Photonic crystals (PhCs) are artificially designed or natural occurring structures with periodic arrays of different materials along at least one crystallographic direction. These structures have periodic variation of refractive indices which results in allowed The journey of research begins with introducing the field of photonics, the major newlinechallenges, possible solutions and motivation and the origin of the problem. While going newlinethrough the immense literature survey, it is noticed that DOM of the tunable PhCs newlinestructure is one of the important properties and has been least focused in the PhCs newlineresearch community.s. newline
