A 4OAMx4WDM switching experiment has been carried out combining an innovative integrated tunable OAM multiplexer based on 4-concentric omega-shaped silicon waveguides and a refractive element-based OAM demultiplexer; operation is demonstrated up to 120Gb/s.
We propose an OAM converter exploiting an innovative integrated OAM multiplexer based on concentric omega-shaped waveguides. The OAM converter, which can operate on signals multiplexed both in OAM and wavelength domain, is successfully tested up to 100Gb/s with real data-traffic.
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.
