Superconducting Opto-Electronic Transmitter Circuit

Published Patent Application Number: 18/203,845

Problem

Diagram showing the circuit for resetting the Spectral Power Distribution (SPD) after the Light Emitting Diode (LED) has emitted a photonic pulse.

Previous inventions allowing superconducting circuits to drive light sources can only operate in a very narrow range of LED device impedances before latching of the circuit becomes a problem.

Invention

This invention describes a family of circuits that receive an input current or voltage pulse when a superconducting element has been driven above threshold, producing an amplified current or voltage pulse to drive a light source, and reset to the resting state after light has been generated.

Potential Commercial Applications

AI hardware; the circuits can be used for highly spatially multiplexed communication.

Competitive Advantage

Complementary metal-oxide-semiconductor (CMOS) technology has a major advantage in this area, as accurate models and modeling techniques are readily available.
