Apparatus, method, and system for a laser-assisted field emission microwave signal generator

摘要

A source electrode is biased to lower the potential barrier of surface electrons. A laser radiates the source electrode, producing a tunneling electron current. The tunneling electron current oscillates in response to frequency of the laser. The impedance match circuit couples the current from a high-impedance source electrode of a laser-assisted field emission to a lower-impedance connector, creating a high-frequency microwave signal source. Two or more lasers may be photomixed to further tune the frequency of the microwave signal.
