Abstract

An optoelectronic feedback structure is introduced to a distributed Bragg reflector mode-locked laser diode (DBR-MLLD) to improve its phase noise performance. Optical pulses with a repetition rate of 40 GHz, a pulse width of 5.2 ps, and a center wavelength tuning range of 4.3 nm are demonstrated. The phase noise of the hybrid mode-locked DBR-MLLD has been reduced by 44 dB to a level of -97 dBc/Hz at a 10 kHz frequency offset from the carrier frequency comparing to the passive mode-locked state.
