摘要:

利用有效折射率法推导计算了全内反射型光子晶体光纤非线性系数与其结构参数——包层空气孔间距、空气孔半径、入射光波长的关系. 得出了全内反射型光子晶体光纤非线性系数与结构参数、入射光波长的关系曲线,并讨论了其对光子晶体光纤非线性系数的影响. 为光子晶体光纤在非线性研究与应用方面提供了理论依据.

关键词: 光子晶体光纤, 非线性系数, 有效折射率

Abstract:

The relationship existed in the nonlinear coefficient, the geometry parameters and wavelength is derived when considering photonic crystal fibers of total internal reflection type with triangle cladding by calculating the effective refractive index. The curves showing the relation are given. The relations of the nonlinear coefficient are discussed. Theoretical support for photonic crystal fibers in nonlinear research and application is provided.

Key words: photonic crystal fiber, nonlinear coefficient, effective refractive index
