Paper Abstract

The paper presents an analysis of planar broadband waveguide interferometers in the case of a change in layer thickness. The analysis was performed for the wavelength range of 450nm-1200nm. The TE0 and TM0 orthogonal modes which propagate in this wavelength range are considered. At the output of the system, an interference signal behind a polarizer can be recorded. If a spectrometer is used as a detector, the recorded signal is a function of the wavelength. Change in the change thickness of the waveguide layers results in a change of the recorded signal shape.
