Dual-wavelength one-directional multimode fiber interferometer with impact localization ability
Abstract
The study of one-directional dual-wavelength distributed mode-mode fiber interferometer with ability of perturbations localization is presented. The working principle's feature is based on excited modes quantity increase along the multimode fiber from the launch point to opposite fiber end. In this configuration output signal characteristics depend on amount of modes at the point of lightguide perturbation. In the investigated optical scheme, modes amount is increasing along the fiber at one wavelength and remains unchanged at the other wavelength as a reference. Theoretical consideration and experimental research results are presented.
