Integrated optical phased arrays (OPAs) enable emission and dynamic control of free-space light in a compact form factor, at low costs, and in a non-mechanical way. Motivated by initial applications in LiDAR sensing for autonomous vehicles, integrated OPA demonstrations so far have primarily focused on systems operating at infrared wavelengths and emphasizing non-mechanically beam steering. There are wide-reaching and high-impact applications including augmented-reality (AR) displays, optical trapping for biphotonics, and 3D printing which require OPAs operating at visible wavelengths and generating complex reconfigurable holographic emission profiles. This work targets corresponding development of novel integrated silicon photonics OPA-based platforms, devices, and systems complemented by proof-of-concept demonstrations of chip-based AR displays, optical traps, and 3D printers. The novel OPAs will impact wide range of consumer, military, and medical applications. The proposed mentoring, outreach, and DEI initiatives will engage and support students with diverse backgrounds at the K12, undergraduate, and graduate level.This project will include novel fundamental-science developments in integrated visible-light OPA-based platforms, devices, and systems, and exploratory proof-of-concept visible-light OPA-based application demonstrations. This will include development of (1) novel OPA-based system architectures that enable reconfigurable holographic emission profiles and compatibility with the entire visible spectrum, including the first visible-light 2D-beam-steering OPAs, active holographic and focusing OPAs; (2) a suite of novel integrated visible-light devices, including the first visible-light liquid-crystal-based modulators for compact and low-power modulation, unidirectional visible-light grating-based antennas for efficient emission, actively-tunable visible-light grating-based antennas, and optimized broadband passive devices for compact spectrum-spanning routing; (3) new 300-mm wafer-scale visible-light fabrication platform with unique transparent and flexible substrate capabilities; and (4) novel visible-light OPA-based application demonstrations, including the first integrated-photonics-based holographic AR display, OPA-based optical trap, and chip-based 3D printer.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

集成光学相控阵列（OPA）能够以紧凑的形状因子、低成本和非机械方式发射和动态控制自由空间光。受自动驾驶汽车LiDAR传感的初始应用的启发，到目前为止，集成OPA演示主要集中在红外波长下运行的系统，并强调非机械光束转向。有广泛和高影响力的应用，包括增强现实（AR）显示器，双光子学的光学捕获和3D打印，这些应用需要在可见波长下工作的OPA并生成复杂的可重构全息发射轮廓。这项工作的目标是相应开发基于OPA的新型集成硅光子学平台、设备和系统，并辅以基于芯片的AR显示器、光学陷阱和3D打印机的概念验证演示。新的OPA将影响广泛的消费者，军事和医疗应用。建议的指导，推广和DEI计划将吸引和支持K12，本科和研究生水平的不同背景的学生。该项目将包括基于可见光OPA的集成平台，设备和系统的新基础科学发展，以及探索性的概念验证基于可见光OPA的应用演示。这将包括开发（1）新的基于OPA的系统架构，其能够实现可重构的全息发射轮廓和与整个可见光谱的兼容性，包括第一个可见光2D光束转向OPA、有源全息和聚焦OPA;（2）一套新颖的集成可见光器件，包括用于紧凑和低功率调制的第一可见光基于液晶的调制器，用于高效发射的单向可见光光栅基天线、可主动调谐的可见光光栅基天线以及用于紧凑型跨谱路由的优化宽带无源器件;（3）具有独特的透明和柔性基板能力的新型300 mm晶圆级可见光制造平台;以及（4）新颖的基于可见光OPA的应用演示，包括第一个基于集成光子学的全息AR显示器，基于OPA的光阱，和芯片-该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查进行评估，被认为值得支持的搜索.
