中文摘要：
将PG玻璃材料制作成的椭圆纤芯引入光子晶体光纤中心,设计了一种石墨烯包层结构的高双折射光子晶体光纤.基于有限元法对该光纤的双折射特性进行了数值模拟,研究了光纤孔径比、孔间距和纤芯椭圆对双折射特性的影响,并以该光子晶体光纤的模场面积和限制性损耗为依据进行了优化.研究结果表明：在波长1 550nm处,光纤双折射率高达0.13,满足高双折射要求;两偏振方向模场面积小于0.7μm2,限制性损耗低于10-6 dB/km.该光纤可有效保持光在传输系统中的偏振状态,为高稳定性超连续谱的产生提供依据.
英文摘要：
By introducing the elliptical hole doped with PG glass into the core of photonic crystal fiber, a graphene structure photonic crystal fiber with high refractive index was proposed. Numerical simulation based on finite element analysis was performed to calculate birefringence in the proposed structure with implementation of different parameters. The effects of air aperture ratio, hole pitch and fiber core ellipse on the fiber＇s birefringent characteristics were studied. Meanwhile, the optimization was performed by the mode areas and confinement loss of photonic crystal fiber. The results show that, at 1 550 nm wavelength, the high birefringence is 0.13, while mode areas are less than 0.7 μm2 and the confinement loss are less than 10-6 dB/km in two modes. The fiber efficiently can protect the polarization in light transmission, providing basis for the realization of super-continuum spectrum of high-stability.
