摘　　要：锥形光子晶体光纤具有色散缓变特性,能有效抑制高斯脉冲展宽,本文利用全矢量等效折射率模型计算了一种全新的锥形光子晶体光纤,研究发现这种锥形光子晶体光纤具有初始色散值可调节性,如设计近零色散和高负色散等,剖面色散为直线型、类指数型等多种可能方式,可以进行色散的自补偿等优点,数值模拟和分析表明这种色散缓变的锥形光子晶体光纤相比传统的色散缓变光纤具有更多的优越性和实用性.The tapered photonic crystal fibers have the characteristic of slowly decreasing dispersion. A vector effective index model is used to analyze the new tapered photonic crystal fibers. Research indicates the initial value dispersion value of the photonic crystal fibers can be regulated, such as nearly zero dispersion, high and negafive dispersion, et al. Profile dispersion has many types, such as linear, Exponential - like, et al. Meanwhile, they have the merit of self - compensation of dispersion. Simulation and analysis reveal that the tapered photonic crystal fibres of slowly decreasing dispersion which compared with traditional ones have more superiority and practicality.
