摘要

光子带隙空心芯光纤（PBG-HCFs）具有较低的相位依赖热敏性，可以达到零或负的延迟热系数（TCDs）。在此之前，我们提出了利用表面模式（SM）工程来调整PBG-HCF的TCD的新概念，并在数值上证明了TCD范围从- 400 ps/km/K到400 ps/km/K [Opt. Express 30, 222-231(2022)]。在本文中，我们设计并制作了一个19电池的PBG-HCF，并在我们所知的范围内首次通过实验证明了PBG-HCF的TCD表面模式调谐。测量到的TCD范围为- 166 ps/km/K至217 ps/km/K，在电信C波段的36 nm传输窗口内。

Demonstration of tuning thermal coefficient of delay of photonic bandgap hollow-core fiber by surface mode

Photonic-bandgap hollow-core fibers (PBG-HCFs) present a low thermal sensitivity of phase dependence, and zero or negative thermal coefficient of delays (TCDs) are possible to reach. Previously, we proposed a new concept of utilizing the surface-mode (SM) engineering in the tuning of TCD of PBG-HCF and numerically demonstrated a broad TCD range from −400 ps/km/K to 400 ps/km/K [Opt. Express 30, 222–231 (2022)]. In this paper, we design and fabricate a 19-cell PBG-HCF, and demonstrate the surface mode tuning of TCD of PBG-HCF by experiment for the first time to the best of our knowledge. A measured TCD range from −166 ps/km/K to 217 ps/km/K is within a 36 nm transmission window at the telecom C band.

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.
