Abstract
We describe the balanced operation of a multiple-quantum-well balanced heterodyne receiver photonic integrated circuit (PIC). Using only SMA-connected 50 Ω commercial electronics, we achieve a free-space beam sensitivity of -42.3 dBm at 108 MbA and -39.7 dBm at 200 MbA for NRZ FSK reception. This represents a 14 dB improvement over any previous heterodyne receiver PIC sensitivity. In addition to providing the multichannel benefits of heterodyne reception, this is also the highest sensitivity yet reported for any OEIC receiver.
