Dynamics and Spectra of Monolithic Mode-Locked Laser Diodes Under External Optical Feedback

Abstract

In this paper, the effect of external optical reflection on the dynamic regimes and spectral properties of Fabry-Perot and distributed Bragg reflector monolithic mode-locked laser diodes is investigated numerically. The relation of the findings to experimental results is discussed, and optimizing the laser construction for reducing the feedback effects is also assessed.
