The authors report here on deterministic single photon emission after coherent optical state preparation in the -shell of a single quantum dot. In the approach, they use -shell Rabi flopping followed by relaxation to the -shell ground state with subsequent spontaneous single photon emission. Pulsed photon correlation experiments show complete suppression of the correlation peak at zero time delay and hence demonstrate clean single photon emission.
