Abstract
An optoelectronic modulator is based on the concentration of an electron beam from an electron gun by a tapered cavity, which sides are photosensitive and change the electrical conductivity under the illumination of light (electromagnetic radiation). The light modulation causes the corresponding changes in the current transported across the walls of the cavity. The remaining part of the electron current exits the cavity aperture and forms an amplitude-modulated divergent electron beam.
Claims10
An apparatus comprising:
- an optically active electron concentrator with an exit aperture;
- an electron source emitting an electron beam towards the optically active electron concentrator;
- and
- a light source aimed at the optically active electron concentrator for modulating output of the electron beam through the exit aperture.
