Design of triangular FBG filter for sensor applications using composite differential evolution

Fiber Bragg grating is one of the most important optical communication optimization problems of current interest. The Triangular FBG Filter (TFBG) can be used as a readout device in FBG-based sensor application. This article describes the application of a recently develop metaheuristic algorithm, known as the composite differential evolution (CoDE), to optimize a TFBG filter design problem for a given grating length. The CoDE has been used to solve a difficult instance of the design problem and the optimization goal in each example is easily achieved. The experimental results of the CoDE algorithm have been shown better than the recently published results obtained using CMAES algorithm is a statistically meaningful way.
