We experimentally demonstrate an efficient information transmission technique using Laguerre Gaussian (LG) modes. This technique is based on multiplexing and demultiplexing multiple LG modes with different azimuthal and radial components. At the reception, the initially sent modes encoding the information are extracted with high fidelity using a complete decomposition allowing to identify a particular mode from a set of modes within a unique iteration. Importantly, we investigate the effects of the atmospheric turbulence on the proposed communication system. We believe that the proposed technique is promising for high-bit-rate spatial division multiplexing in optical fiber and free space communication systems.
我们通过实验证明了一种使用拉盖尔高斯（LG）模式的高效信息传输技术。该技术基于对具有不同方位角和径向分量的多个LG模式进行复用和解复用。在接收端，利用一种完全分解方法以高保真度提取最初发送的编码信息的模式，该方法允许在唯一一次迭代中从一组模式中识别出特定模式。重要的是，我们研究了大气湍流对所提出的通信系统的影响。我们认为，所提出的技术对于光纤和自由空间通信系统中的高比特率空间复用具有广阔前景。
