title = "Accurate finite difference beam propagation method for complex integrated optical structures",
abstract = "A simple and effective finite-difference beam propagation method in a z-varying nonuniform mesh is developed. The accuracy and computation time for this method are compared with a standard finite-difference method for both the 3-D and 2-D versions",
