本文提出了一种具有色散平坦特性的高非线性微结构光纤的理论设计。采用APSS™ 2.3软件，基于完全匹配边界条件的有限差分法，对所提出的微结构光纤的特性进行了模拟。模拟结果表明，该光纤在1550 nm波长处具有41 W − 1 km − 1量级的高非线性系数和0.25ps/nm/km的低色散。它假定在以1550 nm波长为中心的1450- 1620 nm波长范围内具有0±0.50ps/nm/km的色散平坦特性，具有适度数量的设计参数。
This paper presents a theoretical design of highly nonlinear microstructure optical fiber with dispersion-flat characteristics. The APSS™ 2.3 software based on the finite difference method with perfectly matched boundary conditions is used to simulate the properties of the proposed microstructure optical fiber. According to simulation, the proposed fiber warrants a high nonlinear coefficient of the order 41W−1km−1and a low dispersion of 0.25ps/nm/km at 1550nm wavelength. It assumes a dispersion-flat characteristic of 0±0.50ps/nm/km in a 1450–1620nm wavelength range centering 1550nm wavelength with a modest number of design parameters.
