Photonic integrated circuits are developing as key enabling components for high-performance computing and advanced network-on-chip, as well as other emerging technologies such as lab-on-chip sensors, with relevant applications in areas from medicine and biotechnology to aerospace. These demanding applications will require novel features, such as dynamically reconfigurable light pathways, obtained by properly harnessing on-chip optical radiation. In this paper, we introduce a broadband, high directivity (>150), low loss and reconfigurable silicon photonics nanoantenna that fully enables on-chip radiation control. We propose the use of these nanoantennas as versatile building blocks to develop wireless (unguided) silicon photonic devices, which considerably enhance the range of achievable integrated photonic functionalities. As examples of applications, we demonstrate 160 Gbit s data transmission over mm-scale wireless interconnects, a compact low-crosstalk 12-port crossing and electrically reconfigurable pathways via optical beam steering. Moreover, the realization of a flow micro-cytometer for particle characterization demonstrates the smart system integration potential of our approach as lab-on-chip devices.
光子集成电路正在成为高性能计算和先进片上网络的关键使能组件，以及诸如芯片实验室传感器等其他新兴技术的关键使能组件，在从医学、生物技术到航空航天等领域都有相关应用。这些苛刻的应用将需要新颖的特性，例如通过适当利用片上光辐射获得的动态可重构光路。在本文中，我们介绍了一种宽带、高方向性（>150）、低损耗且可重构的硅光子纳米天线，它完全能够实现片上辐射控制。我们提议将这些纳米天线用作通用构建模块来开发无线（非导引）硅光子器件，这将大大扩展可实现的集成光子功能范围。作为应用示例，我们展示了通过毫米级无线互连实现160 Gbit/s的数据传输、一个紧凑的低串扰12端口交叉以及通过光束转向实现的电可重构光路。此外，用于粒子表征的流动微细胞仪的实现展示了我们的方法作为芯片实验室设备的智能系统集成潜力。
