Effects of radiation-mode coherent coupling in integrated optics discontinuities
Abstract:
We study the coupling of radiation modes in successive integrated optical discontinuities. This study is performed for the spectral domain of both the radiation and the guided local modes. Analytical expressions for the coupling between groups of radiation modes themselves for different types of discontinuities are developed. The effect of discretization, required for representation of a physical structure by successive discontinuities, is also studied. This study is a preliminary for the realization of a numerical propagation method. In an application, the effects of coherent coupling of radiation modes in successive abrupt bends are presented.

Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium, μ.
Furthermore, the...
