摘要

本文设计了一种高非线性GeSbS硫族光子晶体光纤，并利用COMSOL多物理场有限元软件对其进行了数值研究。PCFs特别吸引人，因为它们通过将电磁场封闭在强光约束中，为改善体介质的非线性提供了很大的机会。另一个好处是能够通过修改包层中气孔的形状和尺寸来调整材料的分散。数值分析表明，在1.55μm波长处，所设计的PCF在X和Y偏振模式下分别具有3.5 W-1 km-1和4.122 W-1 km-1的高非线性。所设计的硫族化合物基PCF可用于非线性光学应用，如光纤传感器、中红外超连续谱生成和其他光学应用。

Numerical Investigation of Highly Nonlinear and Low Confinement Loss Chalcogenide Photonic Crystal Fiber

In this paper, a high nonlinear GeSbS chalcogenide photonic crystal fiber (PCF) is designed and investigated numerically using COMSOL Multiphysics FEM software. PCFs are particularly appealing because they provide great opportunity to improve the bulk medium's nonlinearity by enclosing the electromagnetic field in a strong light confinement. Another benefit is the ability to tailor material dispersion by modifying the shape and dimension of the air holes in cladding. The numerical analysis demonstrates that the designed PCF provides the high nonlinearity of 3.5 W-1 km-1 and 4.122 W-1 km-1 in X and Y polarization mode, respectively at 1.55μm wavelength. The designed chalcogenide-based PCF can be very useful in non-linear optical applications such as fiber sensors, mid-infrared supercontinuum generation, and other optics application.
