    Abstract

    A variational approach for the modal analysis of dielectric waveguides with arbitrary piecewise constant rectangular 2D cross-section is developed. It is based on a representation of a mode profile as a superposition of all modes of the constituting slab waveguides times some unknown continuous coefficient functions, defined on the entire lateral coordinate axis. The propagation constant and the lateral functions are found from a variational principle. It appears that this method, while preserving the computational efficiency of the standard effective index method, provides more accurate estimates for propagation constants, as well as well-defined continuous approximations for mode profiles.
