Abstract:Layered two-dimensional
(2D) GO films are integrated with silicon-on-insulator (SOI) nanowire
waveguides to experimentally demonstrate an enhanced Kerr nonlinearity,
observed through self-phase modulation (SPM). The GO films are integrated with
SOI nanowires using a large-area, transfer-free, layer-by-layer coating method
that yields precise control of the film thickness. The film placement and
coating length are controlled by opening windows in the silica cladding of the
SOI nanowires. Owing to the strong mod… 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.
