摘要

本文引入了一套增强的经验关系来增强硅基光子晶体光纤的设计过程。这些关系适用于U参数和高阶色散,仅依赖于空气孔直径和波长。通过与时域有限差分法(FDTD)结果的比较,严格验证了这些关系的准确性。这种方法为传统方法提供了一种计算效率高的替代方法,消除了对大量数值模拟、耗时的设计过程和复杂编码的需要。因此,它可以简化和快速地评估PCFs的基本性质和色散特性,使其成为各种非线性应用中色散工程的有力工具。此外,该方法不仅提高了计算效率,而且加快了设计和优化过程,与传统的基于仿真的方法相比具有显著的优势。

Enhanced empirical relations for higher-order dispersions modeling in holey fibers
In this paper, a set of enhanced empirical relations is introduced to enhance the design process of silica-based photonic crystal fibers (PCFs). These relations, which apply to the U parameter and higher-order dispersions, depend solely on the air hole diameter and wavelength. The accuracy of these relations is rigorously validated by comparing them with results obtained from the finite-difference time-domain (FDTD) method. This approach offers a computationally efficient alternative to conventional methods, eliminating the need for extensive numerical simulations, time-consuming design processes, and complex coding. As a result, it enables a simplified and rapid evaluation of the fundamental properties and dispersion characteristics of PCFs, making it a powerful tool for dispersion engineering in various nonlinear applications. Moreover, the method not only improves computational efficiency but also accelerates the design and optimization processes, offering significant advantages over traditional simulation-based approaches.
