IRQUAL · Heterogeneous Integrated Short-wave Infrared Colloidal Quantum Dot Lasers

IRQUAL addresses the critical need for compact, integrated lasers operating in the short-wave infrared (SWIR) spectrum (1.3 2.5 m) for diverse applications such as consumer electronics, automotive, IoT, and AR/VR. Specifically, lasers in the eye-safe window (around 1.4 m and > 2 m) are crucial for LIDAR systems, 3D face recognition, and environmental monitoring. Current technologies, including solid-state lasers and III-V semiconductor laser diodes, face limitations in size, cost, performance and scalability. IRQUAL aims to develop a versatile heterogeneous-integrated laser platform. This platform will exploit SWIR CQD laser technology pumped by established GaAs-based high-power laser diodes to develop a device that covers the range 1.5 to 2.5 m. IRQUAL will further focus on the commercialization and exploitation of the technology described above. To achieve this aim, efforts will be made to develop a strong intellectual property portfolio and also engage with leading industrial figures that could assist in the development and validation of the technology. Achieving IRQUALs objectives will revolutionize SWIR light applications, enabling widespread use in automotive, mobile phones, machine vision, and sensing. Eye-safe illumination systems aligned with safety standards will further enhance commercial prospects. The technology's low-cost and compatibility with consumer electronics laser technology will transform LIDAR, 3D imaging, and remote sensing, contributing to a significant socioeconomic impact. In essence, this project pioneers a new era in SWIR laser technology, introducing unprecedented compactness, cost-effectiveness, and scalability for a multitude of high-impact applications.
