title: Effect of carrier diffusion on the nonlinear response of optical waveguides.
abstract: Using a self-consistent numerical method, we calculate the carrier-density-dependent changes in the propagation constant of a TE mode in a symmetric slab semiconductor waveguide. By modeling the nonlinearity with the plasma theory, the effect of transverse carrier diffusion on the nonlinear response of a waveguide is investigated for typical waveguide parameters.
