Abstract

This tutorial concentrates on third-order nonlinear effects in waveguides and waveguide structures and their applications to all-optical devices. The nonlinear response of few-mode guided wave structures is reviewed. In particular, the principles of operation of nonlinear interferometers, directional couplers, birefringent fibers, and waveguide junctions are explained and recent experimental demonstrations of these systems are reviewed.
