SUPERCONDUCTING OSCILLATOR FOR GENERATING COHERENT ELECTROMAGNETIC RADIATION AND METHOD OF MANUFACTURE THEREOF

摘要

The invention relates to a superconducting oscillator that generates coherent electromagnetic radiation using a nonequilibrium state achieved when current is injected into a high-temperature oxide superconductor. Current is injected through a barrier layer (13) into a single-crystal superconductor (11) having a lamellar structure, and the resulting electromagnetic radiation is amplified in a cavity resonator (5) to produce intense coherent radiation. The superconducting oscillator is capable of amplification and generating coherent electromagnetic radiation simply by supplying direct current without the need for application of a magnetic field.
