Abstract
Abstract Conceptual devices for all-optical self-routeing are discussed, based on particular interference phenomena associated with modified, nonlinear Fabry-Perot cavities. The transmitted amplitude and phase are calculated for cavities composed of III-V semiconductor materials. Within the physical optics approximation the transmission of Gaussian beam profiles and their associated diffraction patterns are obtained. By engineering an asymmetry in the transmitted phase which depends upon the input intensity, an angular deflection of the beam profile can be produced under optical control. The simplest examples indicate that deflections of a beam through several degrees are theoretically feasible. Practical implementations of this effect are discussed.
