论文摘要
轨道角动量多路复用的最新实验证明了其提高光学互连网络中连接能力的潜力。同时，需要紧凑的光子积分轨道角动量（DE-）多路复用设备来解决高可伸缩性，快速可配置，低成本和低功耗。在这里，我们报告了一个大型集成可调的轨道角动量模式多路复用器，该多路复用器在16个波长通道上最多支持20个多路复用轨道角动量模式，并具有30 GHz通道间距。证明了用28 GBAUD编码的9个多路复用的OAM梁的测试床，证明了16季度振幅调制信号，达到了1.008 TBIT S-1汇总速率，较低惩罚和尺寸亚微秒的重新配置速率。该设备提供了一种有效的解决方案，用于替换庞大的衍射光学元件，为光学互连网络中的轨道角动量多路复用铺平了道路。
Recent experiments in orbital angular momentum multiplexing have demonstrated its potential for improving the link capacity in optical interconnection networks. Meanwhile, compact photonic integrated orbital angular momentum (de-)multiplexing devices are needed to address requirements such as high scalability, fast configurability, low cost and low power consumption. Here we report on a large-scale integrated tunable orbital angular momentum mode multiplexer, which supports up to 20 multiplexed orbital angular momentum modes over 16 wavelength channels with 30 GHz channel spacing. A testbed of nine multiplexed OAM beams encoded with 28 Gbaud 16-quadrature amplitude modulation signal is demonstrated, achieving a 1.008 Tbit s-1 aggregated rate with low penalty and sub-microsecond reconfiguration rate of the orbital angular momentum mode. This device offers an effective solution for replacing bulky diffractive optical elements, paving the way for orbital angular momentum multiplexing in optical interconnection networks.
