We demonstrate an integrated InGaAsP/InP mode-locked laser that is stabilized with an optical phase-locked loop (OPLL). Using the OPLL, a single comb line is locked to a reference oscillator (a 200 Hz linewidth Brillouin laser). The comb linewidth is reduced from 100 MHz (unlocked) to %26lt; 550 Hz (locked) using the OPLL. The rms phase error between the comb and reference laser is 20 degrees. The linewidth of the adjacent comb lines is %26lt; 1 kHz, and the comb spans 430 GHz.
