Abstract

Quantum dots have versatile applications in many fields of modern optics, especially in quantum information and communication, on a par with e.g. cold atoms, nitrogen-vacancy centers or organic molecules. In a lot of experimental scenarios, the reliable collection of photons emitted by these quantum objects, the efficient coupling to an incident light field, or both are required. Among others, one possibility to achieve these goals is to place the quantum target in the focus of a deep parabolic mirror. Recently, enhanced photon collection [1] as well as substantial excitation [2] of single ions trapped at the focus of a deep parabolic mirror have been demonstrated.
