We describe a high isolation thin-film filter coated on a GRIN lens surface for triple-play services. High isolations of 60 dB and 43 dB between 1480 nm and 1550 nm bands in transmittance and reflection ports are achieved by use of originally developed ion-beam sputtering deposition machine.
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.
