[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 鹵1 and 鹵2 order OAM signals are transmitted, which can meet the needs of large capacity OAM signal transmission over a long distance.
