We present numerical results showing the effects of a diffusive Kerr-type nonlinearity on the switching characteristics of a nonlinear directional coupler. It is found that switching can still occur even when the diffusion length is equal to the waveguide separation but that then its threshold increases and becomes less pronounced.
