Current short-range optical interconnects capacity is moving from 100 to 400 Gb/s and beyond. Direct modulation of several laser sources is used to minimize bandwidth limitations of current optical and electrical components. This total capacity is pr

We reported 40-Gb/s PAM4 transmission over 10-km SSMF with 2-dB penalty and 6-dBm sensitivity at BER of 2E-4, using directly modulated 1.5-µm VCSEL, with the bandwidth enhancement from 6.4-GHz to 9.35-GHz by offset optical filtering.

We generate a 105.7-Gb/s signal by directly modulating a 1.5-µm VCSEL with a 33.35-Gbaud 3-level signal and polarization multiplexing. By using digital coherent detection, we successfully transmit the 105.7-Gb/s line rate (88.10 Gb/s net bit rate) s
