We present an add-drop multiplexer for WDM nonlinear frequency division multiplexed transmission systems, capable of replacing channels in a modulated spectrum that uses spectral overlap to stitch the nonlinear spectrum to avoid guard bands.
We present add-drop multiplexing for full spectrum modulated WDM nonlinear frequency division multiplexed transmission systems, in which spectral overlap between channels is used to eliminate nonlinear inter-channel crosstalk.
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.
