Abstract
The propagation of electromagnetic fields in straight and circularly curved channel waveguides can elegantly be described in terms of guided modes. They represent non-vanishing solutions of the homogeneous Maxwell equations that propagate without deformation through a waveguide. The source-type integral equation method has already proven to be a powerful method for determining the guided modes of a straight channel waveguide configuration. The method is full-vectorial and mathematically rigorous. In this paper, the method is extended to the circularly curved channel waveguide, as encountered in integrated-optical and opto- electronic devices. A multitude of numerical results is presented.
