Reduction of Relative Intensity Noise of Optical Multicarrier Sources Using External Injection Based Optical Demultiplexer

摘要

In this paper we demonstrate a reduction of relative-intensity noise of a mode-locked laser and a gain-switched comb source based on external injection employing a novel optical demultiplexer. Significant performance improvement is demonstrated in 3.125GBaud, 12.5GBaud and 28GBaud PAM-4 systems.
