Non-resonant cavity-quantum dot coupling

Non-resonant cavity-quantum dot coupling is an interesting phenomenon with significant consequences for solid state single-photon sources. Here we present studies on the origin of the coupling mechanism by resonant excitation of single quantum dots in micro-pillar cavities. Furthermore, we demonstrate the non-resonant coupling as a powerful tool to 'monitor' the s-shell properties of a quantum dot by observing the behavior of a detuned coupled cavity mode.
