This project proposes an optical phased array based on electrically-tunable plasmonic nanoantennas for optical beam steering. There are 3 objectives: (i) to model and design nanoantennas that can be tuned electrically and assembled into a phased array; (ii) to develop nanofabrication processes and to fabricate the arrays, and (iii) to characterise and demonstrate the arrays for optical beam steering. These objectives will be met, initially through the design and modelling of concepts for electrically-tunable plasmonic nanoantennas, then through implementation of arrays of nanoantennas by applying wafer-scale nanofabrication processes using standard semiconductor fabrication tools in a cleanroom setting. The arrays will be tested in a set-up constructed using commercially-available components, custom-machined parts, and software designed and written for array control, data acquisition and processing. Operation of the arrays will be demonstrated by application to beam-steering, initially in one dimension, then, ultimately, in two dimensions. Operating free-space wavelengths to be considered include 1550 nm, which is of interest to telecommunications applications, and 900 nm, which is of interest to Lidar applications. Upon completion of the project, the outcomes, consisting of the technology, its embodiments in the form of optical phased arrays, and the associated electronic control protocols will be transferred to the industrial partner. The benefits to Canadian industry include the provision of a new optical phased array technology for beam steering applications, suitable for optical switching in optical fibre networks or scanning Lidar applications in the automotive sector. The highly-qualified personnel (HQP) formed through this project will develop skills that are highly valued within industry and academia.

该项目提出了一种基于电可调谐等离子体纳米天线的光学相控阵，用于光束转向。有三个目标：（i）建模和设计可以电调谐并组装成相控阵列的纳米天线;（ii）开发纳米制造工艺并制造阵列;以及（iii）验证和演示用于光束转向的阵列。这些目标将得到满足，首先通过设计和建模的概念，电可调等离子体纳米天线，然后通过实施纳米天线阵列，通过应用晶圆级纳米制造工艺，使用标准的半导体制造工具，在洁净室设置。阵列将在使用市售组件、定制加工部件以及为阵列控制、数据采集和处理设计和编写的软件构建的装置中进行测试。阵列的操作将通过应用于波束控制来演示，最初在一维中，然后最终在二维中。要考虑的工作自由空间波长包括电信应用感兴趣的1550 nm和激光雷达应用感兴趣的900 nm。项目完成后，包括技术、光学相控阵列形式的实施方案以及相关电子控制协议在内的成果将转移给工业合作伙伴。对加拿大工业的好处包括为光束转向应用提供新的光学相控阵技术，适用于光纤网络中的光学开关或汽车行业的扫描激光雷达应用。通过该项目形成的高素质人员（HQP）将发展在工业界和学术界高度重视的技能。
