Investigation on propagation and nonlinearity of an octagonal photonic crystal fiber

Abstract

摘要 基于有限元法对一种全内反射型八角光子晶体光纤的传输特性和非线性特性进行了研究，并改变该光子晶体光纤空气孔结构参数得出了其特性与光波长的曲线关系图. 最终得到一种新结构光子晶体光纤，在入射光波长为1.55 μm低损耗窗口处具有非常优越的传输特性和较平坦非线性特性. 关键词: 光子晶体光纤 / 色散 / 损耗 / 非线性系数 Abstract The finite element method is used to investigate the propagation and nonlinearity of octagonal photonic crystal fibers of total internal reflection type.We changed the structural parameters of the fibers and obtained the curves of relations about the propagation and nonlinearity. At last, we found another structure of photonic crystal fiber.It is demonstrated that it is possible to design a low-loss dispersion-flattened PCF at 1.55 micrometer wavelength.
