High responsivity coherent photonic receiver integrating an SOA, a 90° hybrid and high speed UTC photodiodes
16 October 2017
We demonstrate a 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 Gbauds QPSK signals were simultaneously demonstated
