This Alliance project is a collaboration between the Ultrafast Terahertz (THz) Group of Dr. Ménard at the University of Ottawa and OZ Optics Limited, a world-leading company in the development and commercialization of optical components. The partners have a successful history of collaboration that previously resulted in key technical findings to improve THz generation and detection techniques. This project relies on these advances to demonstrate a THz time-domain spectroscopy (THz-TDS) configuration based on a cost-effective ultrafast near-infrared laser. This laser replaces bulky and costly optical sources usually employed in commercial systems. Our goal is to demonstrate a compact and cost-effective THz-TDS configuration accessing a large spectral bandwidth from 0.2 to 6 THz and featuring a high detection sensitivity to characterize materials. The last part of the project will focus on device optimization towards medical diagnostic applications, notably to detect viruses and bacteria. The proposed collaborative project will establish a world-class training environment enabling innovation in the field of THz photonics, a fast growing imaging and characterization optical technology. The project will train undergraduates, graduate students, and one postdoc who will interact with an industrial research team and top-level managers from OZ Optics, to combine new scientific ideas towards the fabrication of a working prototype. Finally, gender balanced and GBA+ will be actively considered during recruitment and training of the research and technical teams.

该联盟项目是渥太华大学 Ménard 博士的超快太赫兹 (THz) 小组与 OZ Optics Limited 之间的合作，OZ Optics Limited 是光学元件开发和商业化领域的世界领先公司，合作伙伴拥有成功的合作历史。先前取得了改进太赫兹产生和检测技术的关键技术成果，该项目依靠这些进步来展示基于经济高效的超快近红外的太赫兹时域光谱（THz-TDS）配置。该激光器取代了商业系统中通常使用的笨重且昂贵的光源，我们的目标是展示一种紧凑且经济高效的 THz-TDS 配置，该配置可访问 0.2 至 6 THz 的大光谱带宽，并具有用于表征材料的高检测灵敏度。该项目的最后一部分将重点关注医疗诊断应用的设备优化，特别是检测病毒和细菌。拟议的合作项目将建立一个世界一流的培训环境，促进太赫兹光子学、快速发展的成像和表征领域的创新。光学的该项目将培训本科生、研究生和一名博士后，他们将与 OZ Optics 的工业研究团队和高层管理人员互动，将新的科学理念结合起来，最终实现性别平衡和 GBA+。在研究和技术团队的招募和培训过程中将积极考虑。
