Dielectric Waveguides

Based on the coupled mode theory and on other analytical and semi-analytical methods we model the propagation of electromagnetic waves in dielectric integrated optical circuits.

Please also have a look at the fabulous collection of in-browser online solvers by our group member Dr. Manfred Hammer.
