Improved two-dimensional beam-propagation method for three-dimensional integrated-optical waveguide structures having rectangular-core cross sections.
An optimized effective index method is combined with a two-dimensional beam-propagation method to form an efficient design tool for integrated-optical waveguide structures with rectangular-core cross sections. The accuracy is evaluated by comparisons with the results from a full three-dimensional beam-propagation method.
