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

  title={Using quasi-guided modes for modeling the transfer behavior of bent dielectric slab waveguides},
  • Published 2010
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 derived as approximate solutions of the exact theory. This work will first give a brief introduction to the basic theory, followed by a discussion of the properties of quasi-guided modes. After a validation by… CONTINUE READING
