  • Steady-state non-equilibrium distribution of free carriers and photon energy up-conversion using same
    Patent number: 7391024
    Abstract: An apparatus is disclosed for the conversion of radiation. The apparatus includes a mesoscopic sized region, an interface surrounding the mesoscopic sized region and contacting the mesoscopic region to form an energetic barrier sufficient to spatially confine free carriers in the mesoscopic sized region, and a matrix material surrounding the interface. At least one of the interface and the matrix material provides radiative recombination of the free carriers.

  • Composite structure providing steady-state non-equilibrium distribution of free carriers and IR system using same for photon energy up-conversion
    Patent number: 7193210
    Abstract: Methods and specialized media adapted to the formation of a steady-state, non-equilibrium distribution of free carriers using mesoscopic classical confinement. Specialized media is silicon-based (e.g., crystalline silicon, amorphous silicon, silicon dioxide) and formed from mesoscopic sized particles embedded with a matrix of wide-bandgap material, such as silicon dioxide. An IR to visible light imaging system is implemented around the foregoing.
