Temperature and strain sensitivity measurements of high-birefringent polarization-maintaining fibers

The strain and temperature sensitivities of three common commercial high-birefringent polarizationmaintaining fibers (bow-tie, polarization-maintaining and absorption-reducing, and elliptical core fibers) have been measured by using a dynamic polarimetric method. The experimental setup and measuring process are described in detail. Where possible, the measuring data are compared with published data, and good agreement is obtained.
