摘要：

A fiber optic strain sensor based on interference between LP01-LP02 modes of a circularly symmetric few mode fiber has been studied. Differential phase shift between the two modes is measured as a function of strain in the fiber with and without coating. A simple theoretical model to estimate the differential phase shift due to strain is also developed, the prediction of which matches well with the experimental results.
