Tunable compound semiconductor lasers for mid-infrared trace gas-sensing

级联激光器，如量子级联激光器（qcl）在环境监测和气体传感等许多应用中变得越来越重要。随着制造商为大众市场开发越来越复杂的技术，“物联网”和“工业4.0”的出现将带来技术和成本方面的挑战。基于CL的传感系统的全球市场预计将从2015年的1.48亿美元增加到2024年的17亿美元（optic.org 2015）。该项目旨在通过采用全新的级联激光器封装方法来颠覆全球CL市场，同时降低成本和降低制造复杂性，同时满足传感系统制造商日益增长的光谱纯度要求。该项目将使英国的传感设备供应链在世界舞台上变得更具竞争力，使其能够在这个高增长领域占据更大的份额。

Cascade Lasers, such as quantum cascade lasers (QCLs) are becoming increasingly important in many applications such as environmental monitoring and gas sensing. The advent of the ‘Intenet of Things’ and ‘Industry 4.0’ will drive both technical and cost challenges as manufacturers develop increasingly sophisiticated technology for a mass market. The global market for CL based sensing systems is predicted to increase from $148m in 2015 to ~ $1.7b by 2024 (optic.org 2015). This project aims to disrupt the global CL market by taking a completely new approach to the packaging of cascade lasers, simulatenously driving down costs and reducing manufacturing complexity whilst meeting the increasing spectral purity requirements of sensing system manufacturers. The project will result in the UK’s supply chain for sensing devices becoming significantly more competitive on the world stage allowing it to capture a larger share of this high growth sector.
