Up to 168-Gb/s PAM-4 direct detection transmission with silicon travelling wave Mach-Zehnder modulator
arXiv:1812.11081
Abstract
Based on a silicon travelling wave Mach-Zehnder modulator, we demonstrate record 168Gb/s (84Gbaud) and 160Gb/s (80Gbaud) PAM-4 direct detection transmission over 1km and 2km SSMF, respectively, with bit error rates below 20% HD-FEC threshold.
