Solitary laser
WebAbstract: Semiconductor lasers are extremely sensitive to optical feedback, which can cause power dropout events (often called low-frequency fluctuations (LFF)) near the solitary laser threshold. In this phenomenon, the laser power suddenly drops to almost zero and then recovers in a stepwise manner to its original power level, only to drop out again at … WebJun 24, 2024 · In this chapter we therefore investigate the timing jitter of the solitary passively mode-locked laser, as well as its behaviour under the influence of optical …
