Query: Fast and efficient demultiplexing of single photons from a quantum dot
  with resonantly enhanced electro-optic modulators   We report on a multi-photon source based on active demultiplexing of single
photons emitted from a resonantly excited GaAs quantum dot. Active
temporal-to-spatial mode demultipexing is implemented via resonantly enhanced
free-space electro-optic modulators, making it possible to route individual
photons at high switching rates of 38 MHz. We demonstrate routing into four
spatial modes with a high end-to-end efficiency of 79% and measure a
four-photon coincidence rate of 0.17 Hz mostly limited by the single-photon
source brightness and not by the efficiency of the demultiplexer itself. We use
the demultiplexer to characterize the pairwise indistinguishability of
consecutively emitted photons from the quantum dot with variable delay time.
