Abstract

In this paper, a low-loss high-birefringence 7-cell photonic-bandgap hollow-core fiber (PBG-HCF) is designed and fabricated based on the method of surface mode engineering. Within a smooth transmission band from 1472 nm to 1560 nm, a minimum attenuation of 39 dB/km is measured where up to 3.29 × 10⁻³ group birefringence is achieved. The windowed Fourier transform (WFT) is applied in the analysis of spectral beating measurement results. The wavelength dependence of group birefringence of fundamental and higher-order modes is resolved.

低损耗7单元光子带隙空心芯光纤中表面模诱导的高双折射

本文基于表面模工程的方法，设计并制作了一种低损耗、高双折射的7单元光子带隙空心芯光纤（PBG-HCF）。在1472 nm至1560 nm的平滑传输波段内，测量到的最小衰减为39 dB/km，达到3.29 × 10−3组双折射。将加窗傅里叶变换（WFT）应用于频谱跳动测量结果的分析。解决了基模和高阶模群双折射的波长依赖性问题。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
