Imec and its partners in the Belgian project Q-Comirse presented the first prototype SWIR sensor based on indium arsenide quantum dot photodiodes. The sensor demonstrated successful 1390nm imaging results, offering an environmentally-friendly alternative to first-generation quantum dots that contain lead, which limited their widespread manufacturing. The proof-of-concept is a critical step toward mass-market infrared imaging with low-cost and non-toxic photodiodes.
