Using quasi-guided modes for modeling the transfer behavior of bent dielectric slab waveguides

The connection of two straight dielectric multimode slab waveguides by a circular bent waveguide is analyzed by means of quasi-guided modes. These modes correspond to the well known leaky modes, but own real eigenvalues, thus the mathematical description is simpler. Furthermore they are deri...
