Paper Abstract

In this work, a study of a new type of optical fiber interferometer with three-beam system has been carried out. Some analyses of the performances of the interferometer have been considered and reported upon. A theoretical model of the optical fiber interferometer and demonstration that such system could be constructed by optical fiber structures are presented. To achieve the goal which ensures higher performance and stability of the interferometer the simulations for intensity noises, phase noise in the interference path and phase shift noise of the certain three-beam optical fiber interferometer have been carried out. The results indicate that the 3×3 coupler is key factor. The optical fiber interferometer could be used to constitute an optical fiber sensor such as optical fiber hydrophones array. Other applications of optical fiber sensor with the three-beam interferometer also have been discussed.
