Abstract

The photonic crystal is a spatial dielectric material in which refractive index of material is periodically modulated. Photonic band gap is the characteristics by which wave is propagated inside this crystal. This chromatic gap of photonic crystal is mainly used for the spatial purpose filtering. In the proposed paper review of various types of optical filter which are based on optical fiber, photonic crystal fiber and photonic crystal material has been discussed. The recent advancement of optical filtering technique and also different applications of optical filter has been reviewed. In the paper advance photonic crystal based Add & Drop filter (ADF) is also explained which is mostly used for filtering purpose in optical communication network and wavelength division multiplexing (WDM).
