Abstract. The paper presents the principle of the operation of a spectropolarimetric interferometer. In a planar waveguide orthogonal modes of the TE and TM types can be excited for the entire visible light. During the propagation the difference of the phases between the modes was determined, which is the function of the length of the path of propagation, the difference of the effective refractive index (NTM-NTE) and the wavelength. At the output of this system the spectral distribution of intensity was recorded, the shape of which depends on the value of the refractive index of the cover of the waveguides.

The paper presents the principle of the operation of a spectropolarimetric interferometer. In the planar waveguide orthogonal modes of type TE and TM can be excited for the entire visible light. Durring 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 the effective refractive index (N TM -N TE ) and the 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.

“…Particularly noteworthy are differential interferometers using a two-mode optical waveguide [2][3][4][5], which in some cases provide greater sensitivity than single-mode waveguides [6]. They operate utilizing the interference of two modes of different orders in the exemplary types of structures: spiral-type waveguides [7], silicon nanowire ridge waveguides (SNRW) [8], composite bimodal waveguides [9]. Modes propagating in a waveguide interfere with each other and the light intensity distribution at the output of the structure depends on the phase difference between the modes.…”
