电磁波最近被探索的一个特性是多重波束的能力，这样每个波束都有一个独特的螺旋相位前。相位前“扭转”量表示轨道角动量态数，不同轨道角动量的光束是正交的。这种基于轨道角动量的多路复用可以通过传输多个同轴数据流，潜在地提高具有单个孔径对的毫米波无线通信链路的系统容量和频谱效率。在这里，我们展示了一个超过2.5米的32 gbit s−1毫米波链路，频谱效率为~16 bit s−1 Hz−1，使用四个独立的轨道角动量光束在两个极化中的每一个上。所有8个轨道角动量通道的恢复误码率低于3.8 × 10−3。此外，我们还演示了一种毫米波轨道角动量模式解复用器，该解复用器可以将串扰小于- 12.5 dB的四个轨道角动量信道解复用，并展示了一个8gbit / s - 1链路，其中每个链路在两个极化上都包含两个轨道角动量光束。利用轨道角动量光束的高速数据传输最近得到了证明。在这里，Yan等人展示了一个32 Gbit/s毫米波通信链路，使用八个同轴传播的独立轨道角动量光束，在两个正交偏振上具有四个轨道角动量状态。
One property of electromagnetic waves that has been recently explored is the ability to multiplex multiple beams, such that each beam has a unique helical phase front. The amount of phase front ‘twisting’ indicates the orbital angular momentum state number, and beams with different orbital angular momentum are orthogonal. Such orbital angular momentum based multiplexing can potentially increase the system capacity and spectral efficiency of millimetre-wave wireless communication links with a single aperture pair by transmitting multiple coaxial data streams. Here we demonstrate a 32-Gbit s−1 millimetre-wave link over 2.5 metres with a spectral efficiency of ~16 bit s−1 Hz−1 using four independent orbital–angular momentum beams on each of two polarizations. All eight orbital angular momentum channels are recovered with bit-error rates below 3.8 × 10−3. In addition, we demonstrate a millimetre-wave orbital angular momentum mode demultiplexer to demultiplex four orbital angular momentum channels with crosstalk less than −12.5 dB and show an 8-Gbit s−1 link containing two orbital angular momentum beams on each of two polarizations. High speed data transmission using orbital angular momentum beams has been recently demonstrated. Here, Yan et al. demonstrate a 32 Gbit/s millimetre-wave communication link using eight coaxially propagating independent orbital angular momentum beams with four orbital angular momentum states on two orthogonal polarizations.
