采用有效折射率模型分析了光子晶体光纤的色散特性 ,并给出了无限大空气玻璃微结构中基模的本征方程 .分析结果表明光子晶体光纤具有奇异的色散特性 ,能在极大的波长范围内支持单模传输 ,在单模工作时可以具有反常波导色散 .同时通过调整光子晶体光纤的结构参数 (包括空气孔径和孔间距 )可以移动零色散点的位置 .最后讨论了大空气孔光子晶体光纤的特性及其在色散补偿中的应用
The effective refractive index model is used to analyze the chromatic dispersion of photonic crystal fiber. The eigenvalue equation of the fundamental mode in the infinite air glass microstructure is given. The analytical results show that the photonic crystal fiber has the singular dispersion characteristics and can be used in the extremely large wavelength Which supports single-mode transmission in the range of single-mode work can have anomalous waveguide dispersion. At the same time by adjusting the photonic crystal fiber structure parameters (including the air aperture and hole spacing) can move the zero-dispersion point position.Finally discussed the large air hole photon Characteristics of Crystal Optical Fiber and Its Application in Dispersion Compensation
