Shortwave infrared (SWIR) light can enable unprecedented reliability, function and performance in high-volume, computer vision first applications in service robotics, automotive and consumer electronics markets. Image sensors with SWIR sensitivity can operate reliably under adverse conditions such as bright sunlight, fog, haze and smoke. Furthermore, the SWIR range provides eye-safe illumination sources and opens up the possibility of detecting material properties through molecular imaging. Colloidal quantum dots (CQD) based image sensor technology offers a promising technology platform to enable high-volume compatible image sensors in the SWIR, however, a fundamental roadblock exists in translating SWIR-sensitive quantum dots into key enabling technology for mass-market applications. In a new study published in Nature Photonics, ICFO researchers have developed a new technology platform that is RoHS compliant and can be integrated with CMOS.
