  • Nested waveguides
    Patent number: 7865048
    Abstract: A radiation source or detector including a nested waveguide structure is provided. A smaller waveguide provides wave guiding for radiation of shorter wavelength. The smaller waveguide is embedded within a larger waveguide that provides wave guiding for radiation of longer wavelength. Wavelength conversion between the shorter wavelength and the longer wavelength can be realized through a nonlinear process.
    Type: Grant
    Filed: September 10, 2008
    Date of Patent: January 4, 2011
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Leon McCaughan, Chad Staus, Thomas F. Kuech
  • Coherent terahertz radiation source
    Patent number: 7515801
    Abstract: A THz radiation source comprising a dual waveguide heterostructure is provided. The dual waveguide heterostructure includes an optical waveguide contained within a larger THz waveguide layered structure. The radiation source provides a coherent guided wave of THz radiation which is generated via difference frequency mixing in a gain medium with a large second-order nonlinearity and propagated with low THz loss by a dielectric medium in the layered waveguide structure. The THz radiation source is compact, has a high power output, and may be operated in continuous-wave (CW) mode at room temperature.
