Abstract :
Subharmonically synchronous mode-locked and hybrid mode-locked lasers suffer from strong amplitude modulation at frequencies corresponding to injection signal frequency. In this paper, we demonstrate for the first time, significant reduction of amplitude modulation of pulse trains generated by a subharmonic synchronous mode-locked laser at 38 GHz using a nonlinear optical loop mirror. Experimental results as well as a theoretical analysis for the scheme are presented.
