Measuring the power distribution among transverse modes of coherent light in optical fibers and excitation of transverse modes or modal groups in a fiber are of practical significance for development and investigation of fiber lasers, sensors and fiber communication lines. The feasibility of mode generation in a step-index optical fiber using binary phase diffractive optical elements (DOEs) is studied. Modes different from the principal mode are selectively excited in the optical fiber using the binary phase DOEs. It is also reasonable to make a computer simulation of mode excitation to predict the behavior of optical system. Simulation results prove theoretical derivations on characteristics of mode excitation. These results are also in a good concordance with experimental ones.
