Abstract:
We report a compact coherent receiver front-end consisting of an integrated 4x40 arrayed-waveguidegrating array following a polarization-diversity hybrid for complete demodulation of a 1.12-Tb/s multi-carrier-signal having 10x112-Gb/s PDM-QPSK subchannels, achieving 17-dB required OSNR/subchannel at BER=10-3.
