Abstract
We report the observation of self-sustained pulsation and transient self-pulsation in laser diodes at 1300 nm and the effect of optoelectronic feedback on the pulsations. Transient self-pulsation has a lifetime of a few minutes with frequencies up to 7 GHz. The linewidth of self-pulsation is on the order of 0.5 GHz. With optoelectronic feedback, the transient self-pulsation can be stabilized and enhanced. The center of frequency of feedback-sustained pulsation is dependent on the passband of the bandpass filter in the feedback loop. The linewidth of feedback-sustained pulsation is significantly reduced to about 20 kHz. The feedback sustained pulsation can be frequency modulated. Applications of the feedback-sustained pulsation subcarrier multiplexed optical networks.
