Abstract :
Characterization of the timing and amplitude (AM) noise have shown a greater than 20-dB reduction of the supermode noise spurs from a harmonically mode-locked laser by continuous-wave optical injection. A reduction of the timing jitter and AM noise from 127 to 25 fs and 0.85% to 0.12% (10 Hz-100 MHz), respectively, is demonstrated. A reduction of the optical linewidth, implied by the reduction in the close-in phase noise, is also shown.
