Abstract
Nowadays, by increasingly using the Dense Wave Division Multiplexing (DWDM) in communication industry, Fiber Bragg Gratings (FBGs) are extensively used in various telecommunication and sensors because of adjustable properties of Bragg wavelength and their bandwidth. In this article, numerical simulation of optical fiber and FBGs is done based on three dimensional algorithm of Finite Difference Time Domain (FDTD). Using this method, propagation of a wave in an optical fiber and a uniform FBG are shown and the results are compared with employing Gaussian apodization on index profile of FBG. Our results show the efficiency of FBGs improves.
