Abstract:

The objective of this work is to investigate the characteristics of dielectric slab waveguides frequently used in integrated optics by a microwave modeling technique. The study includes excitation of a surface wave mode in a low loss dielectric waveguide as well as coupling between two similar degenerate mode and different non-degenerate waveguides. The experimental data indicate the coupling length is short for the non-degenerate, and decreases as the separation between the two guides decreases for either case degenerate or non-degenerate. The authors also investigated the field characteristics outside a curved slab and the containment of radiation. Also included in this work is the investigation of far field pattern for guides with different radii of curvature.
