【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 increase of information, a new optical fiber which can be used for the transmission of photon orbital angular momentum (OAM) is proposed, and its development technology is studied. Plasma chemical vapor deposition (PCVD) technique was used to solve the stress damage problem of high refractive index ring fiber core structure fiber preform rod. Through repeated research and verification, the high steady state wire drawing technology of ring core fiber was formed. The development of the fiber is realized. The fiber has a ring structure. The transmission loss of the fiber can be kept at a low level while the 卤1 and 卤2 order OAM signals are transmitted, which can meet the needs of large capacity OAM signal transmission over a long distance.
