ABSTRACT
We demonstrate a single polarization monolithically integrated coherent receiver on an InP substrate with a SOA preamplifier, a 90° optical hybrid, and four 40 GHz UTC photodiodes. Record performances with responsivity above 4 A/W with low imbalance <1 dB and error free detection of 32 Gbaud QPSK signals were simultaneously demonstrated.
