Alignment of two optical fiber based on particle swarm optimization technique

In this paper, an optical fiber alignment system based on the particle swarm optimization (PSO) technique is developed and presented. The PSO algorithm is used for locating the optimal coupling position with the highest optical power with two-degrees of freedom alignment. This algorithm yields interesting results without a need to go through the complex mathematical modeling of the alignment system. The proposed algorithm is validated considering the alignment of two Single Mode Fibers (SMF) and the alignment of SMF and Photonic Crystal Fiber (PCF) fibers.
