Photonic bands predict the behavior of light accurately

Dr. Brijesh. N. Chawda

Abstract :

In photonic band gap, light cannot enter the crystal because the gap acts as an insulator of light and the light velocity will be changed from velocity of light to zero and thus light and matter interaction is controlled. The existence of photonic band gap is a forbidden gap for photons in which location of light and spontaneous emission of light can be controlled by adding controlled amount of impurities and also by artificially introduced defects which in turn finds wide applications in scientific and engineering fields.
