Low divergence angle and low jitter 40 GHz AlGaInAs/InP 1.55(mu)m mode-locked lasers

摘要

We demonstrate a novel (to the best of our knowledge) 40 GHz passively mode-locked AlGaInAs/InP 1.55(mu)m laser with a low divergence angle (12.7 deg X 26.3 deg), timing jitter of 1.2 ps (10 kHz-100 MHz), and a radio frequency linewidth of 25kHz.
