摘要

在本文中，我们提出了一种八角形光子晶体光纤(PCF)，它有五个环和两个不同直径的圆形气孔，可以产生高的负色散和高的非线性系数。采用有限元方法对所设计的聚光元件的光学特性进行了研究。数值研究表明，在$\pmb{\lambda=1.55\ \mu} \mathbf{m}$处可获得−1449 ps/(nm.km)的色散，适合于光通信网络中的色散补偿。此外，所提出的PCF还具有$\pmb{100.5}\mathbf{W}^{\pmb{-1}}\mathbf{Km}^{\pmb{-1}}$在$\pmb{1.55\mu}\mathbf{m}$波长的高非线性，使其适合于传感应用。进一步研究了结构参数在适当值附近的变化。

Highly Nonlinear Dispersion Compensating Octagonal Photonic Crystal Fiber: Design and Analysis

In this paper, we have presented an octagonal photonic crystal fiber (PCF) having five rings with circular air-holes of two different diameters which can yield high negative chromatic dispersion as well as high nonlinear coefficient. Finite element method has been employed to investigate the optical features of the designed PCF. The numerical investigation indicates that a large dispersion of −1449 ps/(nm.km) is obtained at $\pmb{\lambda=1.55\ \mu} \mathbf{m}$ which makes it suitable for compensating dispersion in optical communication networks. Moreover, the proposed PCF also offers high nonlinearity of $\pmb{100.5}\mathbf{W}^{\pmb{-1}}\mathbf{Km}^{\pmb{-1}}$ at $\pmb{1.55\mu}\mathbf{m}$ wavelength which makes it suitable for sensing application. Furthermore, structural parameter variation around appropriate value is investigated.
