Precision Rulers for the Visible - Chip Scale Optical Frequency Combs

该项目旨在创建一种光子芯片技术，该技术可以在单个芯片上产生数百条可见光谱中的相干激光线，用于精确传感、成像未知物体和测量气体排放。该项目希望在当前的光子芯片技术中引入这种新功能，目前这种技术只能在红外光下工作。预期的结果是廉价、稳定和节能的设备，指甲大小，将实现前所未有的精度测量。这将允许这些设备安装在无人机、卫星和机器人上，使其在国防、信息安全、成像、自动驾驶汽车和传感应用中具有吸引力。

This project aims to create a photonic chip technology that generates hundreds of coherent laser lines in the visible spectrum from a single chip for accurate sensing, imaging unknown objects and measuring gas emissions. The project expects to introduce this new capability in the current photonic chip technology, which currently only operates with infrared light. The expected outcomes are inexpensive, stable and energy-efficient devices the size of a fingernail that will enable measurements with unprecedented accuracies. This should allow these devices to be mounted on drones, satellites, and robots, making them attractive for defence, information security, imaging, autonomous vehicle, and sensing applications.
