Abstract
Two-dimensional all-optical devices include a planar single-mode waveguide formed on or in a major surface of a supporting substrate. The waveguide comprises a nonlinear medium having an intensity-dependent index of refraction. For input optical signals above a critical intensity, self-focusing occurs in the waveguide. Microminiature high-speed bistable and switching devices based on this phenomenon and compatible with integrated-optics technology are thereby provided.
