Paper Abstract

Novel all-optical signal processing devices can be realized by utilizing optical power-dependent refractive-index materials in guided-wave resonators. The resonators are channel waveguide structures that obtain their feedback by means of cleaved mirrors, a corrugation, or a ring geometry. The nonlinear material can be part of the waveguide, of the cladding, or both. As the power carried by the guided wave in the resonator is increased, the effective refractive index of the waveguide changes, the optical path length is modified, and the resonator switches between transmission and reflection states. As a result, the resonator exhibits optical hysteresis, and acts as an intrinsic bistable device. We present the general theory of power-dependent refractive-index waveguides, and apply the theory to some devices that can serve as all-optical signal processors, such as optical amplifiers, discriminators and memory devices.
