Mismatched nonlinear directional couplers with Gaussian type coupling coefficient are investigated. Single-beat length and multiple-beat-length mismatched Gaussian type nonlinear directional couplers are numerically simulated. Their switching curves are compared with those of their constant coefficient counterparts.
