Modal analysis is of the most fundamental importance in the optical waveguide theory, yet modal solutions in exact analytical forms are available only for a limited number of special waveguide geometries. Over the years, there have been rapid advances in optical waveguide technology, and a large number of modal analysis methods have been developed to cope with the increasingly sophisticated waveguide ...
