Abstract

We have characterized the reflectivity, modal discrimination, and passive mode locking performance of diode lasers with intracavity reflectors (ICR) composed of a different number of slots. Upon analysis, we demonstrate that a monolithic semiconductor mode-locked laser comprising a compound cavity formed by a single deeply etched ICR slot fabricated using the 1.55 μm AlGaInAs strained quantum-well material provides the best harmonic (M = 4) mode-locking performance, with Gaussian-pulses generated at a pulse repetition rate of 161.8 GHz and a pulse duration of 1.67 ps, providing a time-bandwidth product of 0.81.
