摘要
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 .
The dispersion properties of photonic crystal fiber (PCF) was analyzed by an effective refractive model, and the eigenvalue equation of the fundamental space-filling mode in infinite air silica micro-structure was presented. The analysis results show that PCF has unusual dispersion property, which can support single mode transmission in a very large wavelength range and have anomalous dispersion under singe mode operation. Zero dispersion wavelength can be shifted by adjusting the structure parameters of PCF. Finally, PCF with large air holes and its applications in dispersion compensation were also discussed.
