The prospect of studying quantum optics in solid state systems has triggered enormous efforts in the development of microcavity structures with embedded quantum dots. The success story in this field of modern optics includes the observation of fundamental light-matter interaction in the cavity quantum electrodynamics regime and the realization of novel nonclassical light sources. Up till now, the respective research has focused almost exclusively on individual microcavities excited optically by rather bulky external laser systems.

In this contribution, we demonstrate a novel approach for on-chip quantum optics using an integrated electrically driven whispering gallery mode microlaser. The latter allows for the observation of Purcell enhancement for an integrated, in-plane pumped quantum-dot microcavity system [1].
