Paper Abstract

The paper presents the principle of operation of the broad-band difference interferometer in the bimodal waveguide. In the planar bimodal waveguide modes fundamental TE0 and TE1 can be excited for the entire range visible light. During the propagation the difference of the phases between the modes is determined, which is the function of the length of the path of propagation, the difference of effective refractive index (NTE0-NTE1) and the optical wavelength. At the output of this system the spectral distribution of intensity is recorded, the shape of which depends on the value of the refractive index of the cover of the waveguides.
