Abstract

In this article we discuss a special operation regime of mode-mode interferometer under selective coherent and continuous excitation of multimode fiber in which number of modes increases along the waveguide. Experimental investigations which demonstrated signal dependencies from number of mode groups propagating at the point of perturbation were carried out. Theoretical model was also developed. The results of the work can be fundamental for a new solution of localization task for distributed optical fiber sensors based on mode-mode interference in multimode optical fiber.
