本文从理论上和实验上研究了一种一端为圆偏振模式，另一端为线偏振模式的光纤。我们称这种光纤为偏振转换光纤，因为它们所代表的本地模式或偏振状态，在光纤中从线性转换为圆形，反之亦然。我们已经开发并实现了一种后处理工艺，用于制作30毫米长的偏振转换光纤样品，损耗小于1 dB，偏振模式从圆形到线性的转换大于20 dB。此外，我们还模拟并测量了偏振变换光纤样品对波长和温度的依赖性。测量到的30mm长样品光纤的归一化波长依赖关系约为1.4 x 10(-4) nm(-1)，测量到的归一化温度依赖关系约为6 x 10（-4）℃（-1）。在某些情况下，这些值比传统的高双折射光纤四分之一波片的值更好。
We have theoretically and experimentally investigated an optical fiber with circular polarization modes on one end and linear polarization modes on the other end. We call this fiber a polarization-transforming fiber because the local modes, or polarization states they represent, are converted from linear to circular, and visa versa, in the fiber. We have developed and implemented a postdraw process for making polarization-transforming fiber samples 30 mm long with losses less than 1 dB and a polarization-mode conversion from circular to linear greater than 20 dB. Also, we have modeled and measured the dependence on wavelength and temperature of polarization-transforming fiber samples. The measured normalized wavelength dependence of a sample fiber 30 mm long was approximately 1.4 x 10(-4) nm(-1), and the measured normalized temperature dependence was approximately 6 x 10(-4) degrees C(-1). These values are better in some cases than values for conventional high-birefringent fiber quarter-wave plates.
