光学轨道角动量数字化检测芯片研究

国家高端制造远景规划战略部署以来，逐渐增长的物联网、大数据和人工智能等宽带消耗型业务给现有通讯系统带来巨大的挑战。利用电磁波轨道角动量这一新维度来编码数字信息可以极大地提升通信容量，然而现有轨道角动量检测技术大多利用庞杂的光路和器件，且都不能与电子信息器件直接兼容。本项目中，我们计划研究纳米耦合共振器的电磁波横向相位梯度响应机制，开创光学轨道角动量探测的新型原理，并基于此构建一款轨道角动量的数字化检测芯片，通过电学的方法实现入射光轨道角动量信息的快速读取和检测。本项目的实施可以为电磁波轨道角动量在高通量数字通信系统中的应用奠定坚实的基础。

Since the strategic deployment of the National High-end Manufacturing Vision Plan, the gradually growing broadband consumable services such as the Internet of Things, big data and artificial intelligence have brought great challenges to the existing communication system. Using the new dimension of electromagnetic wave orbital angular momentum to encode digital information can greatly improve the communication capacity. However, most of the existing orbital angular momentum detection techniques use a large number of optical paths and devices, and none of them can be directly compatible with electronic information devices. In this project, we plan to study the transverse phase gradient response mechanism of electromagnetic wave in nanoscale coupled resonator, create a new principle of optical orbital angular momentum detection, build a digital orbital angular momentum detection chip, and realize the rapid reading and detection of orbital angular momentum information of incident light through electrical methods. The implementation of this project can lay a solid foundation for the application of electromagnetic wave orbital angular momentum in high-throughput digital communication systems.
