本文首次从理论上研究了椭圆包层光子带隙光纤的波导特性。在这样的光纤中容易实现10-3量级的高双折射。系统地研究了包层棒的椭圆率、包层微结构的晶格比以及两种软玻璃的折射率对比度对双折射的贡献。双折射随结构和材料变化的演化表明，我们的高双折射光纤设计可以定制
We theoretically study for the first time the waveguiding properties of an all-solid photonic bandgap fiber with elliptical cladding rods. High birefringence in the order of 10-3 is easily achievable in such fibers. The contributions of the cladding rod's ellipticity, the lattice ratio of the cladding microstructure as well as the index contrast of two soft glasses to the birefringence are systematically evaluated. The evolutions of birefringence with the structure and material variations show that our highly birefringent fiber design can be tailored
