Abstract

An feedback control algorithm based on improved particle swarm optimization algorithm for adaptive polarization mode dispersion (PMD) compensation has been proposed. In order to achieve the global optima of DOP, the aggregating index has been adjusted to maintain the global searching capability of PSO. The immune clone principle has been adopted to maintain the diversity of the swarm. Compared the eye diagram before and after compensation, the opening of the eye diagram has been improved obviously, which demonstrated the effectiveness of the IPSO based feedback control algorithm..
