Abstract:A high-speed moving average integrator in silicon photonics is demonstrated. The integrator is monolithically fabricated with an optical receiver front-end operating at 1550 nm. The design consists of an optical splitter, an optical lowloss delay line to implement a 400 ps delay between the two received bit streams, two SiGe photodiodes, and a 200 fF capacitor. The proposed moving average structure can perform four-bit integration at 10 Gbps. The resulting signal at the output of the integrator is the moving a… 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.
