Novel Photonic Crystal Fiber with High Birefringence and Low Loss
摘要
设计了一种高双折射、低损耗的新型光子晶体光纤。基于全矢量有限元法,通过改变椭圆结构参量对该光子晶体光纤的有效折射率、双折射、色散、损耗和场特性进行分析。结果表明:改变椭圆率可以实现光纤在1300~1500 nm范围内色散点的控制;当椭圆率为0.6时,该光纤在1550 nm处可获得2.55×10-2的高双折射,以及 2.4×10-2 dB/km的低损耗;1300~1500 nm范围内出现1个零色散点。此新型光纤的性能优于传统光纤,在光通信及光纤传感等领域有一定的应用前景。
Abstract
A novel photonic crystal fiber with high birefringence and low loss is designed. Based on full vector finite element method, the effective refractive index, birefringence, dispersion, loss and field properties of the photonic crystal fiber are analyzed when we change the elliptical structure parameters. Results show that dispersion point control of the novel fiber in the range from 1300 nm to 1500 nm can be realized when we change ellipticity. When the ellipticity is 0.6, the fiber has a high birefringence of 2.55×10-2 and low loss of 2.4×10-2 dB/km. A zero dispersion point appears in the range from 1300 nm to 1500 nm. Performance of the novel fiber is better than that of the traditional fiber, and it has a certain application prospect in the field of optical communications and optical fiber sensing.
