We study the dynamics of individual emitters in micro cavities.

The cavity geometry enables us to zoom in on individual emitters and to concentrate and enhance the interaction in a single optical mode (Purcell effect). We search for robust quantum emitters with a nearly degenerate ground state to store and release quantum states of light.
