Abstract
We present in this paper a model for studying the propagation of an optical mode guided by a multilayer structure with variable thicknesses. Starting from the exact expression of electromagnetic field components for the TE and TM modes, and from the effective index seen by a mode, we define a two-dimensional field and an artificial dielectric with a refractive index equal to the effective index of the mode. It is then possible to reduce the problem of a plane guide with slowly varying thickness to the solution of a scalar wave equation for the field component perpendicular to the guide.[Traduit par le journal]Keywords
