Accurate Analysis of Polarization Coupling in Laminated Multilayered Thin Film Optical 3-D Waveguides
نویسندگان
چکیده
Coupled mode theory (CM) is widely applied in integrated optics, while the rigorous Local Mode theory (LM) is less known, being somewhat harder to implement. We compare the two theories in determining polarization coupling inside a laminated rib waveguide made of a-Si:H and SiO2.For moderate optical axis slant (low hybridization) and for fixed layer thickness the two theories show similar results but LM becomes mandatory when hybridization is important.

Theory of Nonlinear s-Polarized Phonon-Polaritons in Multilayered Structures
A theory is presented for the dispersion relations of the nonlinear phonon-polaritons arising when phonons are coupled to the electromagnetic waves in multilayered structures of nonlinear materials. The calculations are applied to a multilayered structure consisting of a thin film surrounded by semi-infinite bounding media where each layer may have a frequency dependent dielectric function and ...
