摘　　要：A high-birefringence fiber,Tb:YAG crystal-derived silica fiber(TYDSF),was fabricated by CO_(2)laser-heating drawing technique.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 maintaining 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.
