摘要
文章采用全矢量有效折射法深入分析了光子晶体光纤结构参数及比例系数对波导色散、总色散的作用,总结了光子晶体光纤色散特性的调整方法,探索出特定色散特性光子晶体光纤的设计方法,并且设计了在800nm处具有近零平坦色散的光子晶体光纤,该光纤对于研究飞秒激光的传输特性和应用具有一定的价值。
In this paper,the effects of the structural parameters and scaling coefficients of photonic crystal fibers on the waveguide dispersion and lumped dispersion are analyzed in depth by using fully vectorial effective index method.The adjustment methods for the photonic crystal fiber dispersion characteristics are summarized,the design method for photonic crystal fibers with specific dispersion characteristics investigated and a photonic crystal fiber with nearly zero flattened dispersion at 800 nm wavelength designed.This fiber is valuable to the study of the propagation properties and applications of femtosecond lasers.
