| Outline of Final Research Achievements |
Main objective of this project is finding a new method for generating photonic NOON state based on quantum dots in coupled-nanocavities, which can be applied to a new technology offering high-resolution optical microscopy with the resolution level below the standard quantum limit. The system exhibits strong optical nonlinearity at few photon level, which can offer better figure of merit compared to conventional devices. Following achievements were obtained:
(1) We have proposed a method for generating photonic NOON state with quantum dot-nanocavity systems, which is extensible to higher photon numbers with N>2. (2) We developed a theory for simulating the effects of spectral filtering on the figure of merit of quantum light source. Changes in the single-photon purity after passing through a spectral filter were analyzed quantitatively. (3) Self-pulsating laser oscillation was found theoretically in nanolasers based on quantum dot-coupled nanocavity systems.
