Room-temperature nine-µm-wavelength photodetectors and GHz-frequency heterodyne receivers

Room-temperature nine-µm-wavelength photodetectors and GHz-frequency heterodyne receivers, Published online: 26 March 2018; doi:10.1038/nature25790

Quantum-well photodetectors fabricated from photonic metamaterials show enhanced room-temperature sensitivity to long-wavelength infrared radiation and produce gigahertz-frequency heterodyne signals when pumped with quantum cascade lasers.
