摘      要：The power-transfer characteristics of a three-waveguide nonlinear directional coupler (NLDC) ave investigated with the beam-propagation method based on the finite-difference scheme. The coupler consists of two outer linear waveguides and a center waveguide with a nonlinear Kerrlike medium. It is shown that the three-waveguide NLDC is useful for constructing a power-dependent power divider, a power-dependent power combiner, and an optical logic element. (C) 1995 John Wiley and Sons, Inc.
