| 摘 要： | 光子晶体光纤日益成为目前研究的热点,但一般只局限于理论上的定性分析,没有进行准确的定量计算.应用平面波法和整胞方法对二维光子晶体光纤进行了全数值模拟,计算了有效折射率、V参数以及波导色散特性.研究了上述参数与光子晶体光纤的结构参量孔距a,相对孔径f等于D/a的关系.显示出光子晶体光纤的无限单模性质和可控色散特性.

| Abstract: | Photonic crystal fiber is a highlight of the modern science research.However,in most papers,only qualitative analysis have been carried out theoretically,and there are few practical quantitative calculation.The group velocity-dispersion of photonic crystal fiber(PCF) is studied with plane wave method(PWM) and supercell method.The effective index of the fundamental filling mode and V value are obtained.With obtained effective index,dispersion is calculated using spline interpolation,according to different relative hole size f and different pitch a.Simulation results prove the monochromic property and controlled dispersion property of a photonic crystal fiber. |
