Abstract:This paper investigates the impact of saturable absorption (SA) on the performance of optical clock recovery using a mode-locked multisection laser diode. Optical clock at 40 GHz is recovered from the multisection laser with SA section operated under a range of bias conditions. The dependence of extinction ratio and timing jitter of the recovered clock on required optical injection power, data rate detuning, and mark ratio is also evaluated under these operation conditions. The experimental results show that s… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
