摘要

介绍了在长途光通信网络中用作色散补偿器的PCF的色散特性。摘要本文用全矢量有效折射率法分析了光子晶体光纤包层变化的影响。计算有效指数有两个重要参数,即气孔直径d和气孔间距d。Λ用波长表示了不同d和值时有效折射率和包层折射率的差异。Λ PCF的另一个影响因素是其单模性,本文分析了不同设计条件下的单模性。众所周知,PCF可以产生很高的负色散。因此,研究表明,通过改变PCF的特征参数,可以使其色散变得更负或更正。色散曲线的斜率随PCF参数的变化而变化。

Dispersion characterization of photon crystal fiber using fully-vectorial effective index method
the dispersion characterization of the PCF, used as a dispersion compensator in long-haul optical communication networks, is presented. Abstract In this paper, the effect of variations in the cladding of photonic crystal fibers (PCF) using fully-vectorial effective index method has analytically been considered. There are two important parameters in calculating effective index, that are air-hole diameter ( ) d and air- hole spacing ( ). Λ The difference of effective index and cladding index has been shown in terms of wavelengths for different values of d and . Λ Another effective factor of PCF is its single-modedness, which is investigated for different design conditions in this analysis. As it is well known that the PCF can develop high negative dispersion. Therefore, It has been shown that dispersion of the PCF can be more negative/positive by changing its characteristic parameters. Also, it is shown that slope of dispersion curve changes with PCF parameters.
