Polarization Insensitive Photonic Integrated 1x4 WDM Wavelength Selective Switch for Optical Networks

Abstract

We experimentally demonstrate a 1x4 WDM polarization-insensitive wavelength selective switch based on bulk SOAs co-integrated with AWGs. Results show a net gain, broadband, and error-free operation with 0.6 dB power penalty up to 25Gbps NRZ-OOK.
