Particle Swarm Optimization Design of Optical Directional Coupler Based on Power Loss Analysis

In this work, possible design is presented as an optimization problem for an optical directional coupler by using particle swarm optimization (PSO). In this PSO design, identical, parallel, lossless and slab optical waveguides are supposed to be coupled to each other weakly. The power loss and the propagation constant change of TE and TM modes in these… CONTINUE READING
