5 September 2014 Surface-plasmon field controlled quantum-dot light absorption and spontaneous emission

The possibility for controlling both the probe-field optical gain and absorption switching as well as photon conversion by a surface-plasmon-polariton near field is explored for a quantum dot located above a metal surface. In contrast to the linear response in the weak-coupling regime, the obtained spectra could show an induced optical gain and a triply-split spontaneous emission peak resulting from the interference between the surface-plasmon field and the probe or self-emitted light field in such a strongly-coupled nonlinear system.
