石墨烯表面等离激元在量子光学领域的应用研究

Due to the exciting electric, mechanic and optical properties, graphene has emerged as a hot topic since its discovery. In particular, graphene plasmons have attracted wide investigations due to the short wavelength, low loss and tunability. In quantum optics area, graphene plasmons also have lots of important applications. In this proposal, firstly, we will investigate the influences of graphene plasmons on some quantum optics phenomena. For instance, the TE-polarized graphene plasmons can enhance the spontaneous emission quantum interference between two orthogonal dipoles. Additionally, we will design some quantum optics devices. By utilizing the strong coupling strength between the localized plasmons and the gain materials near the nanostructure, we aim to combine the graphene nanostructure and gain materials, such as quantum dot and quantum well, to realize continuous variables quantum entanglement between the graphene plasmons and hence construct a new kind of entanglement source. The applications of this kind of entanglement source also will be explored.
