Integrated long cavity mode-locked ring laser with output boost amplifier

Abstract:

We report an integrated 30 mm long cavity mode-locked ring laser at 1555 nm, with a low repetition rate at 2.7 GHz which acts an Optical Frequency Comb Generator (OFCG). The device uses InP-based active-passive integration technology and an output boost amplifier. Passive (PML) and hybrid mode-locked (HML) operation are experimentally demonstrated, with picosecond pulses of 4.65 ps and 4.23 ps pulse-widths respectively. The device exhibits a very narrow RF linewidth of the beat note of few KHz. Also we evaluate the phase noise performance of the fundamental signal generated in both regimes PML and HML.
