Sensing Depth dimension with invisible light capture by colloidal Quantum Dot 

Colloidal Quantum Dot (CQD) technology can revolutionize non-visible imaging which is not accessible with silicon technology. It can offer exceptional performance at low-cost enabled by wafer-level monolithic integration. Markets include robotics, automotive, AR/VR and consumer electronics. Potential use cases include advanced face identification, eye tracking, night vision, advanced driver assistance systems (ADAS), multispectral machine vision for medical and industrial markets. CQD technology has shown excellent performance in SWIR imaging and its process has been made compatible with semiconductor manufacturing in a complementary metal oxide-semiconductor (CMOS) fab, and potentially high detectivity and high speed, making it more interesting for sensing (e.g. 3D/depth). Development of CQD Photodetector (CQDPD) is ongoing within imec targeting a fast photoresponse time. One of the most interesting application case will be doing the depth sensing based on gated imaging from this high speed performance at SWIR wavelengths, where the low solar radiation background and less light absorption or scattering is expected to have higher signal to noise ratio, thus better depth resolution, and maximum detection range.
