Enhancing the photoluminescence properties of single epitaxial gaas quantum dots using optical antennas

摘要

The light emission properties of a single quantum system may be significantly modified by placing the emitter close to a nanostructure. Plasmon resonant metal structures are particularly interesting as the electromagnetic field may be significantly enhanced at the plasmon resonance. This allows controlling, e.g., the excitation and emission rate [1] as well as the emission pattern of the emitter [2], offering exciting possibilities in both fundamental light-matter studies as well as in applications.
