Abstract

Presented is a fabrication technique, alternative to epitaxial liftoff, which enhances the performance of THz antenna detectors and allows building probe structures on top of the antenna dipole by means of etching of GaAs substrate. When used as emitters, a sample to be imaged can be brought as close as 1 μm to the THz emission point. The application of these devices for THz near-field-imaging will be discussed.
