23.6 A 112Gb/s NRZ Heterodyne Detection 23ns Settled Burst-Mode RX with CD Suppression and Envelope Demodulation for 100G PON
Abstract
This work presents a burst-mode receiver based on an intensity modulation heterodyne detection scheme. SSB quadrature IF generation and envelope detection enhance baseband signal integrity and chromatic dispersion tolerance. Pre/post-demodulator loop separation allows parallel AGC/AOC in burst-mode. The SiGe BiCMOS front-end, co-integrated with an O-band silicon photonic PIC, achieves$112 \text{Gb} / \mathrm{s}$NRZ with −25.8 dBm OMA (B2B), 23ns settling, and$-23.7 /-22.9 \text{dBm}$OMA over 20 km SMF in$1290 / 1329 \text{nm}$.
