Here researchers report an integrated detection device for terahertz near-field imaging in which all the necessary detection components, that is, an aperture, a probe and a terahertz detector, are integrated on one cryogenically cooled, semiconductor chip. This scheme enables highly sensitive, high-resolution detection of the evanescent field and promises new capabilities for high-resolution terahertz imaging.
