摘要

We measure phase and group modal birefringence and also polarimetric strain sensitivity in a three-mode elliptical-core fiber for all spatial modes. Our results show a very high difference in fiber sensitivity to strain versus mode order, which is negative for the E_(11) mode and positive for E_(31) mode. We also model all measured parameters using Optiwave BPM-Cad and Cosmos/M software packages. The measured values of phase and group modal birefringence agree well with those obtained from calculations for all spatial modes. We do not observe as good an agreement between experimental and calculated values of strain sensitivity, which is most probably caused by the lack of reliable material constants for SiO_(2)/GeO_(2) glasses.
