Optimization of apodization profile of chirped fiber Bragg grating for chromatic dispersion compensation: Dispersion compensation using chirped apodized FBG

Abstract

In this paper, we have presented the optimization of hyperbolic-tangent profile for fiber Bragg grating (FBG) as dispersion compensator in optical fiber communication system. We have shown that the optimized profile can compensate for chromatic dispersion up to 2237 ps/nm at 1550 nm. The traditional dispersion compensating fiber (DCF) based compensation system can be replaced by this FBG based model which offers many advantages.
