摘要

为解决信息量快速增长带来的传输容量不足问题,提出了一种可用于光子轨道角动量(OAM)传输的新型光纤,并对其研制技术进行了研究。采用等离子体化学气相沉积(PCVD)技术解决了高折射率环形纤芯结构光纤预制棒应力损伤难题,通过反复的工艺研究与验证,形成了环形纤芯光纤高稳态拉丝工艺技术,实现了该光纤的研制。该光纤具有环形结构,在实现±1、±2阶OAM信号传输的同时,光纤的传输损耗仍能保持较低的水平,可满足较长距离的OAM大容量信号传输需求。

Abstract

In order to solve the problem of insufficient transmission capacity caused by the rapid growth of information, we propose and investigate a new type of optical fiber is proposed for photon Orbital Angular Momentum (OAM) transmission. The PCVD technique is used to solve the problem of stress damage of optical fiber preform with high refractive index circular core structure. Through repeated process research and verification, the high steady fiber drawing technology suitable for ring core fiber is demonstrated to manufacture the fiber successfully. The fiber has a ring structure with ± 1 and ± 2 order OAM signal transmission at the same time. The fiber transmission loss can still maintain a relatively small level, which can meet the longer scale OAM large-capacity signal transmission.
