摘　　要：Fiber quarter-wave plates and magneto-optical fibers are important components that greatly affect the sensitivity of fiberoptic current sensors.A Tb:YAG crystal-derived silica fiber(TYDSF)was fabricated using a CO_(2) laser-heating drawing technique.The linear birefringence of TYDSF was measured as 6.661×10^(-6)by a microscope birefringence measurement instrument.A fiber quarter-wave plate was fabricated by TYDSF at 1310 nm,which produced circularly polarized light with a polarization extinction ratio of 0.34 d B.Additionally,the linear birefringence of TYDSF was decreased by 22%by annealing at 750℃ for 7 h,and the Verdet constants of annealed TYDSF were measured to be 9.83,6.67,and 3.48 rad/(T·m)at 808,980,and 1310 nm,respectively.
