The transmission characteristic of Sangac loop interferometer based on single polarization fiber

We were experimental demonstrated the transmission characteristic of Sagnac loop mirror based on single polarization fiber (SPF). The interference fringe of Sagnac loop mirror was not revealed at specified wavelength range, because of SPF with cutoff polarization states. The sensitivities of Sagnac loop mirror based on SPF applied strain and temperature was measured to be 0.72 nm/m and 2.24 nm/°C, respectively.
