Abstract

A fast and reliable method to calibrate LiNbO3-based polarization controllers (PCs) presented theoretically and experimentally. Particle swarm optimization (PSO) algorithm is used as an adaptive searching algorithm. Experimental results show that PSO algorithm is powerful in calibrating LiNbO3-based multistage PCs. Only less than one minute is spent for all stages of the PC to be calibrated thoroughly.
