| Outline of Final Research Achievements |
In this study, I have investigated the non-linear optical interaction between the biexcitons in semiconductors and the entangled photon pairs. In particular, the photon-pair generation and resonant absorption processes were precisely observed.
From the result of the joint spectroscopy for the two-photon emission, the frequency entanglement of the two photons from the biexciton are clearly observed for the first time. Furthermore, the quantum (polarization) correlation in the absorption process is also demonstrated by the systematic measurement of the variation of the biexciton two-photon absorption with polarization basis of the excitation photons.
