| Research Abstract |
Theoretical and experimental research work was performed aiming at implementation of strong-confinement buried waveguides in ferroelectric crystals and nonlinear-optic quantum photonic devices for applications to quantum information processing. Fabrication techniques for waveguides of bonding/ diffusion and ridge types and short-period quasi-phase matching structures were developed. Novel devices such as a twin-photon generation(TPG) device for single photon generation, a tunable TPG device, and polarization-entangled TPG devices were proposed and demonstrated.
