Abstract
An apparatus for producing a single photon can comprise a modulator that modulates the wavelength of a pump beam based on wavelength of an idler photon of a signal/idler photon pair. A wavelength division multiplexer combines the modulated pump beam and the signal photon in a non-linear element to produce an output photon having a preselected wavelength based on signal photon wavelength and a wavelength of the modulated pump beam.
