摘要

基于轨道角动量（OAM）的多路复用技术利用光场的空间信息，为扩大光通信容量和提高频谱效率提供了潜力。本文提出了一种具有沟槽辅助环芯的非零色散位移光纤，用于优化色散管理。研究了各种参数对光纤色散的影响。在1550 nm处，EH ${}_{\mathbf{1,1}}$模式的最小色散为2.42 ps/nm/km, HE ${}_{\mathbf{14,1}}$模式的最大色散为8.71 ps/nm/km。共有50种OAM模式符合ITU-T G.655.C标准，差分模式延迟保持在4.25 ps/m以下。此外，该光纤的有效模式面积超过982 $\mu $ m ${}^{\mathbf{2}}$，非线性系数低于$7.23\乘以10$ ${}^{\mathbf {-4}}$ /W/m，确保了对OAM模式传输的强大支持。

Non-Zero Dispersion-Shifted Fiber With Trench-Assisted Ring Core for Orbital Angular Momentum Modes

Orbital angular momentum (OAM) based multiplexing technology leverages the spatial information of optical fields, offering potential for expanding optical communication capacity and improving spectral efficiency. In this work, a non-zero dispersion-shifted fiber with trench-assisted ring core is proposed for optimized dispersion management. The impact of various parameters on the chromatic dispersion of fiber is investigated. At 1550 nm, the designed fiber exhibits a minimum dispersion of 2.42 ps/nm/km for the EH

${}_{\mathbf {1,1}}$

mode and a maximum dispersion of 8.71 ps/nm/km for the HE

${}_{\mathbf {14,1}}$

mode. A total of 50 OAM modes adhere to the ITU-T G.655.C standard, with differential mode delays maintained below 4.25 ps/m. Additionally, the fiber features an effective mode area exceeding 982

$\mu $

${}^{\mathbf {2}}$

and a nonlinearity coefficient below

$7.23\times 10$

${}^{\mathbf {-4}}$

/W/m, ensuring robust support for OAM mode transmission.

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
