Abstract

We report 4th order colliding pulse mode-locked laser based on InAs/GaAs QD structure, which can generate ultra-stable optical frequency combs in O-band with 100 GHz spacing and a record-high 3 dB optical bandwidth of 11.5 nm (20 comb lines) at 25 °C. Single channel NRZ modulation rates of 70 Gb/s and PAM-4 of 40 GBaud/s are also demonstrated.
