Abstract
The structures under study are thin polymer layers deposited on planar waveguides. Such coatings are generally used within waveguide sensors. Because of the low refractive index and sub-waveguide thickness they cannot guide the light, but they influence the modal propagation of light when deposited on the planar waveguide. Measurement of the coupling angles to these structures for different wavelengths yields values of the effective indices to the two dispersion equations with two unknowns and results in evaluation of parameters of the structure.
