【摘要】：提出一种液晶填充碲酸盐玻璃的柚子型光子晶体光纤偏振旋转器,利用全矢量有限元法,对液晶填充碲酸盐玻璃的柚子型光子晶体光纤的偏振旋转特性进行数值模拟,并分析了光纤结构参数、环境温度、工作波长等对光纤偏振旋转特性的影响.研究结果表明:此种偏振旋转器具有较高的旋转效率、较低的工作串扰和较短的旋转长度,在工作波长为1.55μm、偏振角度为45°时,其值分别达到99.947%、-32.84dB和197μm;另外,随着光纤薄壁厚度的增加,旋转长度随之升高,随着工作波长的变大,旋转长度随之降低,随着温度的增加,旋转长度随之升高.这种新型的光子晶体光纤为偏振旋转器的研发提供了参考.
[Abstract]:A grapefruit photonic crystal fiber polarization rotator with liquid crystal filled tellurite glass is proposed. The polarization rotation characteristics of grapefruit photonic crystal fiber filled with liquid crystal tellurite glass are numerically simulated by full vector finite element method.The effects of fiber structure parameters, ambient temperature and operating wavelength on the polarization rotation characteristics of the fiber are analyzed.The results show that the polarization rotator has higher rotation efficiency, lower crosstalk and shorter rotation length. When the working wavelength is 1.55 渭 m and the polarization angle is 45 掳, its values are 99.947 ~ 32.84 dB and 197 渭 m, respectively.With the increase of the thickness of thin-walled fiber, the rotation length increases, the rotation length decreases with the increase of the working wavelength, and the rotation length increases with the increase of temperature.This new photonic crystal fiber provides a reference for the development of polarization rotator.
