Abstract

We demonstrate a high output power passively mode-locked distributed Bragg reflector laser with integrated tapered semiconductor optical amplifier, operating at 1.5 μm. These devices are based on an optimized low-optical-confinement AlGaInAs/InP epitaxial material with a three quantum wells active region and a passive far-field reduction layer. The device generates nearly transform-limited pulses with minimum pulse duration of 4.3 ps at 40-GHz repetition rate. An average output power of 200 mW with a corresponding output peak power of >;1.2 W is achieved.
