Paper Abstract

A multimode channel waveguide that branches into several single-mode channels can route each of the modes of the multimode waveguide into a different single-mode channel. Such branches are useful for performing a variety of functions in guided wave optoelectronic devices. The two basic functions on which such devices rely are routing and its inverse, selective mode excitation. (For example, switching is time-dependent routing.) We describe the fundamentals of routing and selective mode excitation, and then analyze the performance of proposed two-and three-channel optical switches using parameters appropriate for GaAs. Because of the larger induced changes of refractive index that are possible in this material, we find that such switches can be substantially shorter than in other materials such as LiNbO3.
