Outline of Final Research Achievements

Localized electronic states with a substantial dipole moment is essential to build a quantum interface between photon and crystal. In particular, excitons bound with impurities in a semiconductor is equivalent to an ultimate quantum dot showing extremely uniform photoemission. In this work, we produce two-dimensionally ordered nitrogen centers utilizing a nitrogen delta-doping technique we developed. That enables to produce on-demand entangled photon emission at 0.85 micro-m optical communication band. Furthermore, with combining a micro-cavity structure, we develop a technology controlling photon radiation performance.
