Tunable, Superconducting, Surface-Emitting Teraherz Source

View page
US Patent:
7715892, May 11, 2010
Filed:
Oct 26, 2009
Appl. No.:
12/605997
Inventors:
Ulrich Welp - Lisle IL, US
Alexei E. Koshelev - Bolingbrook IL, US
Kenneth E. Gray - Naperville IL, US
Wai-Kwong Kwok - Evanston IL, US
Vitalii Vlasko-Vlasov - Downers Grove IL, US
Assignee:
Uchicago Argonne, LLC - Chicago IL
International Classification:
H01L 39/08
H01L 39/22
G01R 33/02
US Classification:
505190, 505193, 324248, 2503362, 343700 R, 34087018
Abstract:
A compact, solid-state THz source based on the driven Josephson vortex lattice in a highly anisotropic superconductor such as BiSrCaCuOthat allows cw emission at tunable frequency. A second order metallic Bragg grating is used to achieve impedance matching and to induce surface emission of THz-radiation from a BiSrCaCuOsample. Steering of the emitted THz beam is accomplished by tuning the Josephson vortex spacing around the grating period using a superimposed magnetic control field.

Superconducting Source For Tunable Coherent Terahertz Radiation

US Patent:
8026487, Sep 27, 2011
Filed:
Dec 21, 2007
Appl. No.:
11/963532
Inventors:
Alexei E. Koshelev - Bolingbrook IL, US
Lutfi Ozyuzer - Izmir, TR
Cihan Kurter - Westmont IL, US
Ulrich Welp - Lisle IL, US
Wai-Kwong Kwok - Evanston IL, US
Kenneth E. Gray - Naperville IL, US
Assignee:
UChicago Argonne, LLC - Chicago IL
International Classification:
G01J 5/02
US Classification:
2503418
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. ).

US Patent:
8633472, Jan 21, 2014
Filed:
Sep 14, 2009
Appl. No.:
12/541073

International Classification:
H01L 27/18
US Classification:
257 31, 505100, 505110, 505120, 505121, 505125, 505180, 505181, 505190, 505329
Abstract:
Terahertz radiation source and method of producing terahertz radiation, said source comprising a junction stack, said junction stack comprising a crystalline material comprising a plurality of self-synchronized intrinsic Josephson junctions; an electrically conductive material in contact with two opposing sides of said crystalline material; and a substrate layer disposed upon at least a portion of both the crystalline material and the electrically-conductive material, wherein the crystalline material has a c-axis which is parallel to the substrate layer, and wherein the source emits at least 1 mW of power.
