Long cavity hybrid InP/SiN mode-locked lasers

In this paper, we present a 1.19 GHz integrated mode locked laser based on III-V/Si 3 N 4 butt-coupling. We report the results of active mode locking and harmonic mode locking up to the 2nd harmonic. We also present the preliminary results on another mode locked lasers at repetition rate 360 MHz. To the best of our knowledge, this laser is the lowest repetition rate for an integrated hybrid laser on III-V/Si 3 N 4 .
