The waveguiding characteristics of a novel power switch with one input and n outputs (1×n) using oblique incidence to a nonlinear slab is proposed. With a proper incident optical power, the emitted soliton in the nonlinear slab can be efficiently directed to any waveguide in a array of n waveguides. For digital signal switching application, the number n can be increased simply by increasing the slab thickness. Moreover, it is found that the soliton offsets calculated by Snell’s law with an index obtained by averaging over the index distribution are in good agreement with those calculated by the beam propagation method.
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.
