Abstract In this paper, a novel hybrid hexagonal Photonic Crystal Fibre(PCF), which harnesses the golden ratio for its elliptical core design, is proposed. This work aspires to exploit circular air holes in the construction of PCF. It aids not only to achieve the desired properties but also to curtail the extravagant efforts needed for the fabrication. The Finite Element Method is used to analyze the properties of the proposed PCF. The proposed PCF possesses a negative dispersion of −270 ps/nm.km, a very high birefringence of 2.3 × 10-2, a high numerical aperture of 0.49, and a large nonlinear coefficient of 50.58 W-1km−1 at the desired wavelength of 1.55 μm used for optical communication. The fabrication tolerance of ± 1–2% variation in air hole diameter is also investigated. The proposed PCF with very high birefringence and a large nonlinear coefficient will be an inevitable candidate for optical broadband communication.

一种用于光纤通信的新型混合六方光子晶体光纤

摘要 在本文中，提出了一种利用黄金分割率进行椭圆纤芯设计的新型混合六方光子晶体光纤（PCF）。这项工作渴望在 PCF 的构造中利用圆形气孔。它不仅有助于实现所需的性能，还有助于减少制造所需的大量工作。有限元方法用于分析所提出的 PCF 的特性。所提出的 PCF 具有 -270 ps/nm.km 的负色散、2.3 × 10-2 的非常高的双折射、0.49 的高数值孔径以及在所需波长下 50.58 W-1km-1 的大非线性系数1.55 μm 用于光通信。还研究了气孔直径± 1-2% 变化的制造公差。
