Ultra-thin light detectors: Metamaterials and quantum cascade structures combined for first time

A new, extremely thin kind of light detectors has been developed. Two very different technologies were combined for the first time: metamaterials and quantum cascade structures. Subtle interactions of electrons and light make them so valuable for technology: ultra-thin systems of semiconductor layers can turn electrical voltage into light. But they can also be used the other way around and serve as light detectors.
