A high-birefringence fiber,Tb:YAG crystal-derived silica fiber[TYDSF],was fabricated by CO2 laser-heating drawing tech-nique.Its linear birefringence was 2.99 × 10-5,and it was used to fabricate an all-fiber quarter-wave plate[QWP]device.The polarization extinction ratio[PER]of the device was 0.29 dB,and its ellipticity was 44.26° at 25℃.In the temperature range of-5℃ to 200℃,its PER was always less than 0.80 dB,and the fluctuation of PER and ellipticity was also small.Compared with QWPs fabricated with PANDA-type polarization-maintaining fiber[PMF]and elliptical-core PMF,the performance of TYDSF QWP was least sensitive to temperature.Furthermore,the TYDSF QWP was used in a high-power laser system,still main-taining good circular polarization state,and the nonlinear effects were suppressed in the system.The experimental results are of great significance to high-power lasers,fiber-optic current sensors,etc.,in harsh environments.
