50 GBaud QPSK 0.98 pJ/bit Receiver in 45 nm CMOS and 90 nm Silicon Photonics
Low-power O-band receivers are required for next-generation coherent intra-datacenter interconnects. In this paper, a 0.98 pJ/bit QPSK receiver using a 45 nm CMOS process and a 90 nm Silicon Photonics (SiP) process is demonstrated at up to 50 GBaud.
