Source-type integral equation analysis of circularly curved channel waveguides in a multilayered background

The source-type integral equation method has proven to be a powerful modeling tool for straight ridge waveguides. This method is full-vectorial and mathematically rigorous. In a previous publication the source-type integral equation method has also been successfully applied to circularly curved channel waveguides in a homogeneous background. In the present paper this approach is extended to circularly curved channel waveguides embedded in a multilayered background. These are the type of waveguide structures that are usually encountered in integrated-optical and optoelectronic devices.<
