Abstract: A single-photon Raman optical frequency comb source is provided, including: a light source assembly, a filtering mechanism, at least three electro-optical modulators, a wavelength division multiplexer and a single photon generating mechanism. The light source assembly is configured to generate a Raman scattering light. The filtering mechanism is configured to pass a light having a specific wavelength, to filter the Raman scattering light and obtain at least three Raman scattering spectral lines. Each electro-optical modulator is configured to modulate a frequency of one of the Raman scattering spectrum lines in one-to-one correspondence, so as to cause a frequency shift of the Raman scattering spectrum line. The wavelength division multiplexer is configured to multiplex all modulated Raman scattering spectral lines and output a Raman optical frequency comb. The single photon generating mechanism is configured to adjust the Raman optical frequency comb to obtain a single-photon Raman optical frequency comb.
