✦ Synopsis

We present an 80-GHz λ ∼ 1.55 μm passively colliding-pulse mode-locked laser based on a novel Al-GaInAs/InP epitaxial structure, which consists of a strained 3quantum-well active layer incorporated with a passive far-field reduction layer. The device generated 910 fs pulses with a stateof-art timing jitter value of 190 fs (4 -80 MHz), while demonstrating a low divergence angle (12.7 • ×26.3 • ) with two fold butt coupling efficiency to a flat cleaved single mode fiber when compared with the conventional mode-locked laser.
