Photonic Crystal Principles And Aplications In Nanophotonics

Throughout the last two decades the studies on photonic crystal have made a tremendous developmentsrnin many aspects of physics, specifically in the field of nanophotonics.rnMoreover,many principles andrnapplications of photonic crystal are appearing to be valid in different area of studies. Photonic crystalsrnare microscopic dielectric materials by which light is to be trapped,confined or controlled as it tends tornpropagates through them. In this project, we review the historical development of photonic crystals,rnmetalic photonic crystals and plasmoics, Maxwell equations and the inspirations of bandgap, thernpropagation of light in different media such as one , two and three dimensional media of photonic bandrngap materials(photonic crystals). Our study has fully, concentrated on the progresses, developments ofrnprinciples and technological applications of photonic band gap material. Finally, we have predictedrnthat electromagnetic waves( light modes) can be guided to a desired direction and in a desired mannerrncarrying ample information by the help of different devices that appropriately exploit the properties ofrnphotonic crystals
