Keywords:

Optical switches and channel selecting/routing devices for photonic networks,Planar lightwave circuits (PLCs)

We propose a perfect crossbar optical switch based on cascaded Mach-Zehnder interferometers, which gives no crosstalk at both cross and bar states even if the power ratio of the couplers deviates from 50:50.
