Titel
Novel digital optical switch with crosstalk below -40 dB based on absorptive switching
Abstract
We report a novel space switch carried out in dilated Benes architecture. The switch makes use of absorption and refractive index change provided in MQW layers and shows an extinction ratio of 40 dB.
