Abstract :
LP01-LP02 intermodal interference in a conventional communication optical fiber has been studied theoretically and experimentally. The visibility of the interferometer and its dependence on the detection scheme and the relative excitation efficiencies of the LP01 and LP02 modes have been theoretically considered under the assumption of a Gaussian modal distribution. The results of the experimental investigation of the response to longitudinal strain, temperature, and hydrostatic pressure are reported
