Abstract
LP01-LP02 intermodal interference in highly birefringent (Hi-Bi) elliptical jacket and bow-tie optical fibers was studied experimentally. The response of the interferometer to strain was measured for different polarization inputs. The experiments are shown to agree with a previous theoretical investigation of LP01-LP02 intermodal polarization interference. The modal distributions of the interfering modes are found to be different in elliptical-core and in bow-tie fibers. Comparison with the LP01-LP11 interferometric response is presented. Optimum detection schemes are suggested to extract maximum information from the strain-modulated sensor signal.
