Abstract

The paper presents the theoretical and experimental results involving the influence of refractive index profile on the interaction of modes with the absorption sensitive film. The attenuation distribution of modes in planar waveguides with absorption cover depends on the shape of refractive index profile. In particular, the character of this distribution depends on the location of turning points of particular modes. In the structures with gradient refractive index profiles, the dependence of modes attenuation on their order can be a non-monotonic function.
