We propose a fast and accurate estimation method of MDL-induced SNR penalty with non-uniform noise loading in SDM link. The proposed approach substantially saves the time cost while maintaining an estimation error within 0.2 dB.
We propose multi-task learning based NN equalization for nonlinearity compensation in coherent opticalsystem. Compared with conventional NN equalization, 30% complexity reduction is achieved in an 800-Gb/s PDM-16QAM ...

We propose multi-task learning based NN equalization for nonlinearity compensation in coherent opticalsystem. Compared with conventional NN equalization, 30% complexity reduction is achieved in an 800-Gb/s PDM-16QAM system with 5 output symbols.
Micro-bending with random curvature is usually used to model the mode coupling in few mode fiber (FMF). However, previous models overlooked the accompanied mode dependent loss (MDL) and neglected the order constraints...

We propose and experimentally demonstrate an efficient equalization-enhanced phase noise compensation scheme for long-haul coherent transmission. The distance is extended by 1780km and 470km for $\mathbf{788.4}-\mathbf{Gb}/\mathbf{s}/\boldsymbol{\lambda}$ and 968.4- $\mathbf{Gb}/\mathbf{s}/\boldsymbol{\lambda}$ line rate WDM transmission, respectively, using 3-MHz LO and receiver-side dispersion compensation.
We demonstrate a hybrid-integrated self-injection-locked laser on the Si3N4-on-SOI platform to generate FMCW signal with 9 kHz linewidth, 2 MHz repetition rate, and high linearity, supporting FMCW-LiDAR with refresh r...
