Abstract

We characterized the reflectivity and the modal discrimination of intracavity reflectors (ICRs) with different numbers of slots and presented harmonic mode-locking operation of a monolithic semiconductor laser comprising a compound cavity formed by a single deeply etched slot ICR fabricated from $1.55\mathrm{\mu m}$ AlGaInAs strained quantum well material. Gaussian pulses were generated at a $161.8\mathrm{GHz}$ repetition rate with a pulse duration of $1.67\mathrm{ps}$ and a time–bandwidth product of 0.81.
