有在短波长区域的异常分散的 Photonic 水晶纤维(PCF ) 为一些应用是重要的,例如短波长 soliton 繁殖,超级连续统产生和放射激光的短脉搏纤维。在这份报纸,为与要求的异常分散区域设计 PCF 的一个系统的方法被使用一个有限差别解答者和 PCF 的波导分散的可伸缩的转变建议。设计 PCF 能在这个区域是反常地散的不到 1.3 渭 m,它是很困难的在传统的标准单个模式的纤维认识到。建议方法的有效性被数字结果同意。CLC 数字 TN253 -TQ342+.82 文件代码 A 这个工作被中国(号码 60407011 和号码 60277018 ) 和浙江的国家自然科学基础支持中国的省的自然科学基础(没有。Y104073 )
Photonic crystal fibers (PCFs) with anomalous dispersion in short wavelength region are significant for some applications, such as short wavelength soliton propagation, super continuum generation and short pulse fiber lasing. In this paper, a systematic method for designing PCFs with required anomalous dispersion region is proposed by using a finite difference solver and the scaling transformation of the waveguide dispersion of PCFs. Designed PCF can be anomalously dispersive in the region less than 1.3 μm,which is very difficult to realize in the traditional standard single-mode fibers. The effectiveness of the proposed method is approved by numerical results.
