Designing optical filter with absorption effect by using PSO algorithm

In this paper for optimum designing of optical Broad Band Pass Filter has been used Particle Swarm Optimizer (PSO) algorithm. Because of wide search space, this algorithm in compared with other algorithms is one of the best methods. In present paper, we have described the PSO algorithm and State by bring extraction of two material absorber Zns, ZnSe. Then in first experiment, the PSO algorithm has been used for designing optical broad band pass filter in wavelength 375-750 nm without absorption factor. Afterwards this filter surveyed with absorption factor and again designed with two low absorber materials. The obtained results by use of this method have more convergence rate and higher performance of other methods.
