【摘要】 A high-birefringence fiber, Tb:YAG crystal-derived silica fiber（TYDSF）, was fabricated by CO₂laser-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°C. In the temperature range of-5°C to 200°C, 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.更多还原
