Fiber quarter-wave plates and magneto-optical fibers are important components that greatly affect the sensitivity of fiber-optic 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 \times 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 dB. Additionally, the linear birefringence of TYDSF was decreased by 22% by annealing at 750°C for 7 h, and the Verdet constants of annealed TYDSF were measured to be 9.83, 6.67, and

3.48 rad / (T \cdot m)

at 808, 980, and 1310 nm, respectively.

The spin effect on a single-mode single-polarization optical fiber is investigated theoretically and numerically. To get a practical single elliptically polarized fiber the normalized spin rate must be in the range of 0.2–0.35. A single elliptically polarized fiber with a normalized spin rate around 0.224 is demonstrated. It has a broad band from 1.530 to 1.558 μm, in which the low-leakage elliptically polarized eigenmode loss is kept within 1.2 dB while the high-leakage elliptically polarized eigenmode loss is greater than 20 dB. This fiber can be used as an elliptical polarizer or applied in current sensing.

基于自主研制的掺铋光纤，对其进行光谱特性的实验和理论研究。通过实验测得的吸收光谱发现了4 个明显的吸收带，其中心分别是494、816、946、1410 nm。运用Giles 模型对此光纤进行了放大特性的研究，分析了光纤长度、抽运功率和输入信号光功率等参数对信号的增益和噪声指数的影响。建立了稳态情况下三能级跃迁模型的速率方程和传输方程，并利用Runge-Kutta算法进行了数值研究。结果表明掺铋光纤在波长为830 nm 、功率为200 mW的光波抽运时，1384~1480 nm 波段的增益系数大于1.5 dB/m，噪声系数趋近5 dB。

A single-mode polymer optical fiber (POF) with highly photosensitive core doped with benzil dimethyl ketal (BDK) is fabricated and used for writing Bragg grating through the two-beam interference method. The Bragg wavelength of the grating is about 1570 nm, while the full-width at half-maximum (FWHM) of the reflection peak is 0.3 nm. The temperature response of POF Bragg grating is theoretically analyzed and experimentally measured in contrast to silica optical fiber Bragg grating (FBG). The result shows that the temperature character of POF Bragg grating is negative, which is opposite to the silica optical FBG. The absolute value of the temperature response of POF Bragg grating is one order of magnitude higher than that of the silica optical FBG, making POF Bragg grating appear to be very attractive for constructing temperature sensors with high resolution.
