| Research Abstract |
Based on the strong second-order optical nonlinearity and the exciton-photon interaction in wide-gap semiconductors such as nitrides, fundamental technologies for realizing novel quantum optically correlated photon pair sources have been developed, which will be operated via optical parametric down conversion and resonant hyper parametric scattering processes. Especially the successful demonstration of the high-efficiency violet-colored second harmonic generation from a quasi-phase-matched GaN waveguide with a periodic-polarity-inverted structure attested the applicability of this material system to the quantum optical devices.
