Abstract: A device including a photon emitter, a light source, and a filter with a corresponding method for producing triggered single photons and triggered pairs of polarization-entangled photons are provided. The light source delivers a pulse to a photon emitter and generates pairs of electrons and holes to emit photons. The light source includes a mechanism to tune a pulse wavelength to an excited state-absorption resonance of the photon emitter. The light source could also include a device to selectively choose a polarization to create the pairs of electrons and holes of a particular spin. A filter isolates the last and single photon. Optionally, a micro-cavity is included to direct the emitted photons and couple to one or more optical elements. When the device or the method is used to produce triggered pairs of polarization-entangled photons, it works almost the same as for the single photons, except for modifications to the way the light source excites the photon emitter and how emission filtering is performed.
