Each year, tens of thousands of deaths in Canada and the U.S. are caused by alcohol-impaired driving, spurring global efforts to develop in-vehicle technologies that will detect blood alcohol concentration and reduce the occurrence of these tragic (and completely preventable) accidents. The proposed project brings together researchers from the University of Waterloo and Alcohol Countermeasure Systems Corp. (ACS), a Toronto-based company, to develop a novel middle-infrared quantum cascade laser that can be used as a customized and efficient light source for ACS' infrared-spectroscopy based alcohol detection system, which have strong potential as non-contact alcohol interlocks in vehicles. The goal of this project will be to develop and test a working prototype laser device both theoretically and experimentally. Key objectives include: 1) development of a comprehensive knowledge base about the underlying physics of intersubband transition and electron-electron, electron-phonon interactions occurring in the quantum semiconductor heterostructures; 2) to explore and design new quantum structures that can be used for the desired middle infrared laser source; 3) to fabricate and characterize quantum cascade lasers that satisfy the needs from ACS and the industry. Development and implementation of these novel technologies will help establish a leadership position for ACS and Canada within this growing niche market and promote driver, passenger and pedestrian safety worldwide. This project will also provide an excellent opportunity for graduate students to gain hands-on experience with optical components, alcohol monitoring technologies and in-vehicle technologies - all important skills for careers in the strategically important sectors (electronics, automotive, manufacture, photonics) to the Canadian economy.

在加拿大和美国，每年都有数万人死于酒后驾车，这促使全球努力开发车载技术，以检测血液酒精浓度，减少这些悲剧性（完全可以预防的）事故的发生。拟议的项目汇集了滑铁卢大学和多伦多公司酒精对策系统公司（ACS）的研究人员，开发一种新型的中红外量子级联激光器，可用作ACS基于红外光谱的酒精检测系统的定制和高效光源，该系统具有很强的潜力作为车辆中的非接触式酒精联锁装置。该项目的目标是在理论和实验上开发和测试一个工作原型激光装置。主要目标包括：1）开发关于量子半导体异质结构中发生的子带间跃迁和电子-电子，电子-声子相互作用的基础物理的综合知识库; 2）探索和设计可用于所需中红外激光源的新量子结构; 3）制造和表征满足ACS和工业需求的量子级联激光器。这些新技术的开发和实施将有助于ACS和加拿大在这个不断增长的利基市场中建立领导地位，并促进全球驾驶员、乘客和行人的安全。该项目还将为研究生提供一个极好的机会，获得光学元件，酒精监测技术和车载技术的实践经验-所有重要技能都是加拿大经济战略重要部门（电子，汽车，制造，光子学）的职业生涯。
