Abstract

We demonstrate a high responsivity intradyne coherent receiver engine with 80 GHz bandwidth. A co-design of the InP waveguide integrated coherent photodetector and the dual linear SiGe transimpedance amplifier results in a flat frequency response. A system evaluation at 128 GBaud shows the capability for QPSK and 16QAM.
