Abstract

Ring-Shape-Hole Photonic Crystal Waveguides (RSHPCW) is a popular structure in designing opticalbuffers attracted many attentions recently. There are some parameters such as the radii of holes andpillars next to the defect that have significant effects on slow light properties. Consequently, one ofthe promising methods for effectively slowing the light speed down and controlling dispersion is tooptimize these parameters, which is the motivation of this study. Particle Swarm Optimization (PSO)algorithm is one of the best proposed heuristic optimization algorithms in Artificial Intelligence appliedto many engineering problem. In this work, this algorithm is employed to find the best values of theaforementioned radii for maximizing Normalized Delay-Bandwidth Product (NDBP) of RSHPCW structureas the first systematic optimizer. Calculation results show that there are 34% and 41% improvement inNDBP and bandwidth compared to the previous works, very substantial achievements in this area.Crown Copyright .
