Monolithically integrated 2.5 GHz extended cavity mode-locked ring laser with intracavity phase modulators.

A mode-locked extended cavity quantum well ring laser at 1.58 μm with a repetition rate of 2.5 GHz in the form of a photonic integrated circuit is presented.

Record bandwidth and sub-picosecond pulses from a monolithically integrated mode-locked quantum well ring laser.

In this paper, we present the detailed characterization of a semiconductor ring passively mode-locked laser with a 20 GHz repetition rate that was realized as an indium phosphide based photonic integrated circuit (PIC). Various dynamical regimes as a function of operating conditions were explored in the spectral and time domain. A record bandwidth of the optical coherent comb from a quantum well based device of 11.
