The paper presents the characteristics of a broad-band difference interferometer (spectropolarimetric). When a waveguide layer introduces light from a spectral range, at the output structure there is a spectral distribution which depends on the parameters of the propagation wavelength. It shows the effect of temperature on the parameters describing the system.
