Abstract:Semiconductor optical amplifiers (SOAs) have a number of attractive properties for use in photonic switches. SOAs offer nanosecond switching times, extinction ratios in excess of 40 dB, and small signal gains of approximately 15 dB. In addition they can be monolithically integrated, and thus can potentially be fabricated in volume and used in large switch matrices. Here we report on our recent demonstration of an 8×8 optical crossbar switch based upon discrete SOAs. Other authors [1-3] have reported on SOA-bas… 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.
