Monolithically integrated nonlinear Sagnac interferometerandits application as a 20 Gbit/s all-optical demultiplexer

Abstract

A Sagnac interferometer consisting of a semiconductor laser amplifier and a 3 dB coupler monolithically integrated within a waveguide loop mirror is fabricated and its application as a 20 Gbit/s all-optical demultiplexer is demonstrated.
