| Outline of Final Research Achievements |
The purpose of this study is to theoretically demonstrate a coherent emission of visible light associated with up-conversion of the incoherent infrared sunlight by using quantum mechanical coupling of optical antennas and molecules. Base on this purpose, we have obtained the following results: Rapid truncation of incident light after the continuous excitation of molecules (that are coupled with the antenna), the up-converted photo-emission occurs from the inversely populated molecules. If the number of molecules is large enough, the emission becomes superfluorescence; namely, the coherent light is emitted, which indicates our achievement of purpose. Further, we have successfully developed a new theoretical method to study the cooperative emission from the spatially dispersed molecular ensemble in the geometrically designed mediators.
