Abstract

An innovation long period grating (LPG) synthesis method based on intelligent particle swarm optimization (PSO) algorithm is demonstrated to be very effective for designing optimized LPG filters. A flatten 3dB loss spectrum LPG is designed as an example to show the effectiveness of the PSO algorithm. This 3dB LPG is a key component of multi-channel filter in optical communications and optical sensors. The results showed that the intelligent PSO algorithm is very powerful and can be used for complex optimization problem.
