Paper Abstract

We proposed a new all-optical phase-controlled routing switch contain a two-mode tapered waveguide with the nonlinear cladding. This all-optical device is divided into three sections: the input section, the uniform nonlinear medium section, and the output section. In the input section, the two-mode tapered waveguide is in the center between the linear substrate and the nonlinear cladding. The uniform nonlinear medium section is between the input section and the output section. In this nonlinear medium section, the spatial solitons can be excited. In the output section, three nonlinear guides are used to couple out the spatial soliton excited in the uniform nonlinear medium. The swing effect of the spatial soliton is observed in the uniform nonlinear medium section. By properly controlling the relative phase between the TE0 and TE1 waves, the proposed waveguide device could really function as an all-optical switch.
