Single-photon Fourier spectroscopy of excitons and biexcitons in single quantum dots

Phys. Rev. B, 69(16):165307.

We report on the direct measurement of the linewidth of the exciton and biexciton emission in single self-assembled InP quantum dots. The measurements were performed using a Michelson interferometer combined with a Hanbury-Brown and Twiss correlator. The setup allowed to demonstrate single-photon emission from single dots by detecting antibunching and to determine the coherence length of single photons emitted from the very same dots. A charge-coupled device camera used as detector in the Michelson interferometer allowed to determine the emission linewidth of many dots in parallel under identical experimental conditions at different temperatures.
