摘　　要：研究了包层为单轴各向异性晶体材料且其主轴沿光纤轴线的光纤模型.针对HE11模,运用矢量精确解法分析了各向异性材料对包层中传输能量的影响.结果表明,各向异性材料折射率对该种光纤芯层和包层中传输的能量影响显著.　A model of optical fiber with uniaxial anisotropic cladding,which is coaxial with the axis of the optical fiber,is investigated.Aiming at the HE(11) mode,the influence of anisotropic material on power transmission in the cladding is analyzed by means of vectorial accurate solution.The result shows that the refractivity of anisotropic material has a remarkable influence on the power transmission within the core and cladding of this kind of optical fiber.
