In this work we analyze the birefringence matrix developed for a twisted fiber in order to identify the basic optical effects that define its birefringence. The study was performed using differential Jones calculus. The resultant differential matrix showed three independent types of birefringence: circular, linear at 0 degrees and linear at 45 degrees (Jones birefringence). We applied this birefringence matrix to the description of the output state of polarization measured for three commercial fibers that due to its higher rigidity present stronger birefringence changes when twisted. The torsion applied to the erbium-doped fiber samples varied from 0 to 1440 degrees.
在这项工作中，我们分析了为扭曲光纤开发的双折射矩阵，以识别定义其双折射的基本光学效应。该研究使用微分琼斯演算进行。所得的微分矩阵显示出三种独立的双折射类型：圆双折射、0度线性双折射和45度线性双折射（琼斯双折射）。我们将此双折射矩阵应用于描述三种商用光纤的输出偏振态，由于其较高的刚性，这些光纤在扭曲时会出现更强的双折射变化。施加到掺铒光纤样品上的扭转角度从0度变化到1440度。
