Abstract

Both continuous and discrete particle swarm optimization (PSO) algorithms are applied to design cascaded Mach-Zehnder interferometer (MZI) based optical filter

for the first time.Then the optimal structural parameters (i.e.coupling angles and phase-shift factors) are obtained

by approaching the ideal coefficients with coupling angles and phase-shift factors.In our experiment

a filter of 3-cascaded MZI has been shown

and the relative error between the obtained response and ideal response is about 10

-5

.Meanwhile

compared with genetic algorithm (GA) scheme

the PSO scheme is characterized by short computing time

excellent approach fitness and high extinction ratio.
