title: Self-switching of solitons in an AlGaAs nanowire coupler.
abstract: We propose the design of an AlGaAs-nanowire-based coupler. We demonstrate that it can be used as a useful soliton switching device at the telecommunication wavelength of 1550 nm. Our analysis shows that nonlinear loss due to two-photon and three-photon absorption has almost no effect on the transmission characteristics of the coupler. The linear loss and the self-steepening effect can be made insignificant with a judicious choice of the initial pulse width and operating wavelength.
