  • Photon pair generating apparatus and photon pair generating method
    Patent number: 8441719
    Abstract: In a photon pair generating apparatus for generating a pair of correlated photons by hyper-parametric scattering, a light-shaping section irradiates an optical resonator with two beams of light of equal wavelength from different directions, and the optical resonator is configured to emit two correlated photons of different wavelengths in one direction as a pair of correlated photons. This makes it possible to provide a photon pair generating apparatus capable of achieving generation of a pair of correlated photons by a simpler configuration.
    Type: Grant
    Filed: April 28, 2009
    Date of Patent: May 14, 2013
    Assignee: Osaka Prefecture University Public Corporation
    Inventors: Goro Oohata, Hisaki Oka, Hajime Ishihara
