摘要：

Measurements on multielectrode distributed feedback (DFB) lasers without a saturable absorber reveal the:existence of a self-pulsation (SP) regime, In this regime, the laser remains in the same single-longitudinal mode with simultaneous intensity and frequency modulation, The laser spectrum is similar to that of a current-modulated single-mode laser, At the up-limit of the SP regime, the behavior between the output power and the injection current becomes bistable. In one branch of the bistable loop, the SP laser presents a very large spectrum without distinguishable peaks, a kind of chaotic state with coherence collapse, A qualitative explanation based on the effective differential gain is given for the origin of SP and associated phenomena in these lasers.
