  • Superconducting source for tunable coherent terahertz radiation
    Patent number: 8026487
    Abstract: A system includes a solid state source of THz radiation and a detector. The source of THz radiation may be based on a superconducting material, such as materials containing one or more Josephson junctions (e.g. BSCCO). The source may include a crystal of superconducting material on which a mesa of superconducting material is formed. The resonant coupling between the Josephson oscillations and the fundamental cavity mode of the mesa may lead to synchronization of the Josephson junctions and emission of powerful THz radiation. The mesa may be formed and/or handled such that THz radiation can be emitted by the material without requiring application of an external magnetic field (e.g. the mesa may include a non-uniform compositional gradient, a non-uniform shape, may have radiation non-uniformly applied to the mesa, etc.).
