摘要： An electric device operable with a THz-range frequency of the device output is presented. The device comprises a photocathode installed in either one of a diode, triode and tetrode configuration, and is exposed to illumination. In some embodiments of the invention, the device is configured as a diode and photomixing is used for illumination of the photocathode with light in the THz range, the diode converting this input light signal into an electrical output in the THz range, which operates a signal transmitter/receiver. In some other embodiments of the invention, the device is configured as a triode or tetrode, where the electrodes have small dimensions (about 1 micron or less) and are spaced from one another a distance not exceeding 1 micron. The photocathode is kept under certain illumination, and electrical signal applied to one of the electrodes results in the THz output at one of the other electrodes.
