Wavelength selective, polarization sensitive, and uncooled infrared detectors for solar infrared imaging

Thermoelectrically coupled nanoantennas (TECNAs) for mid- to far-infrared radiation are developed to study the Sun. TECNAs are resonantly absorbing the IR radiation using a nanoantenna that provides wavelength and polarization selectivity, as well as providing uncooled, and fast detection. This technology will enable transient solar measurements in the mid- to far- and wavelength ranges.
