Miniaturized infrared detectors

Integration on a chip: Tremendous effects on spectrometers of different kinds – and in various fields

31-Oct-2022 - Extreme miniaturization of infrared (IR) detectors is critical for their integration into next-generation consumer electronics, wearables and ultra-small satellites. Thus far, however, IR detectors have relied on bulky (and expensive) materials and technologies. A team of scientists lead by Empa ...

Mini-spectrometer: Smaller than a coin

09-Oct-2019 - ETH researchers have developed a compact infrared spectrometer. It’s small enough to fit on a computer chip but can still open up interesting possibilities – in space and in everyday life. Nowadays, a mobile phone can do almost anything: take photos or video, send messages, determine its present ...
