The Efficiency of the Three-Layer Magneto-Optical Sandwiches for Tuning Guided Modes
A. V. Lavrinenko, D. N. Shyroki, and V. V. Zhilko

Using the formalism of an operator method of effective medium, we examine the waveguiding conditions in magneto-optical sandwiches of planar geometry. The structures under consideration contain ultrathin absorbing magnetized film bounded between two dielectric layers. We show that form anisotropy of the structure leads to practically important effect---intersection of modal dispersion curves at certain frequencies and angles of propagation. The influence of absorption and the possibility to control polarization states of the eigenwaves are also discussed.
Key words: planar optical waveguide, effective medium, dispersion relation, guided modes
