In this work, we propose an 8-channel arrayed waveguide grating (AWG) designed for synchronized de-multiplexing of both polarization and wavelength. The AWG device is fabricated on a 220 nm-thick top-silicon Silicon-On-Insulator (SOI) wafer using a straightforward single-etch process. It demonstrate...
