Abstract
We have demonstrated some of our recent results on semiconductor optical amplifier (SOA)-based integrated devices for photonic routers: a WDM channel selector and a wavelength converter. The monolithically integrated 64-channel selector on InP substrate has a novel configuration that allows it to handle a large number of WDM channels. Zero insertion loss, small sensitivity penalties with a typical value of 1.3 dB, and fast channel switching of less than 1.5 ns were realized in the fabricated device. The all.-optical wavelength converter incorporates a Sagnac interferometer integrated with parallel-amplifier structure (SIPAS). Filter-free all-optical wavelength conversion was successfully demonstrated using the fabricated SIPAS.
