空间域被认为是光波在光通信中唯一已知的物理维度。近年来，人们致力于利用光纤的空间模式来提高光纤通信中的数据传输容量。在本文中，我们提出并证明了一种不同的方法来利用空间维，即传输图像的空间维编码/解码使用的空间模式的叠加在千米级少模光纤。通过采用4种模式，即LP 01、LP 11 a、LP 11 b的三个线偏振（LP）模式和OAM（-1）的一个轨道角动量（OAM）模式，或2种模式（OAM（+1）、OAM（-1）），成功地通过1.1 km少模光纤传输三幅灰度图像。误码率的评估和零错误之间的所有接收数据实现，显示出良好的光纤链路通信性能使用光纤的空间模式的编码/解码。此外，我们还演示了4个模式（LP 01，LP 11 a，LP 11b和OAM（-1））的编码/解码的图像传输在10公里的少模光纤在实验中。(C)2016美国光学学会
Space domain is regarded as the only known physical dimension left of lightwave to exploit in optical communications. Recently, lots of research efforts have been devoted to using spatial modes of fibers to increase data transmission capacity in optical fiber communications. In this paper, we propose and demonstrate a different approach to exploiting the space dimension, i.e. transferring image by space dimension encoding/decoding using superpositions of spatial modes in km-scale few-mode fiber. Three grayscale images are successfully transmitted through a 1.1-km few-mode fiber by employing either 4 modes, i.e. three linearly polarized (LP) modes of LP01, LP11a, LP11b and one orbital angular momentum (OAM) mode of OAM(-1), or 2 modes (OAM(+1), OAM(-1)). The bit-error rate is evaluated and zero error among all received data is achieved, showing favorable fiber link communication performance using the spatial modes of fiber for encoding/decoding. Moreover, we also demonstrate the 4 modes (LP01, LP11a, LP11b and OAM(-1)) encoding/decoding for image transfer in a 10-km few-mode fiber in the experiment. (C) 2016 Optical Society of America
