8 × 2nm Polarization-Independent WDM Detector Based on Compact Arrayed Waveguide Demultiplexer

Abstract

We report the first polarization-independent monolithic WDM detector. 8 × 2nm channels, from 1.544μm to 1.558μm wavelength, were demultiplexed and detected by the compact 3.7mm × 4.0mm device without measurable polarization-sensitivity.
