Abstract
An electronic device comprising an optical gate, an electrical input an electrical output and a wide bandgap material positioned between the electrical input and the electrical output to control an amount of current flowing between the electrical input and the electrical output in response to a stimulus received at the optical gate can be used in wideband telecommunication applications in transmission of multi-channel signals.
Claims12
An electronic device, comprising:
- an electrical power supply;
- a first electrode coupled to the electrical power supply;
- a second electrode separated from the first electrode;
- a wide bandgap photoconductive material located between and in contact with the first and second electrodes and responsive to input radiation to change an electrical conductivity of an electrical path between the first and second electrodes through the wide bandgap photoconductive material;
- a radiation source that produces the input radiation received by the wide bandgap photoconductive material;
- and
- an electrical to optical conversion device that receives a sample of an electrical output signal from the first or second electrode and converts the received sample of the electrical output signal into an optical signal that is applied with the input radiation into the wide bandgap photoconductive material to form a closed signal loop to sustain a self-oscillation in the electronic device.
