Single photon sources use anti-bunched light to produce single photons, and in this article an application is described. With a light emitter diode (LED) as a low cost single photon source using weak light coherent pulses, the appropriate use of radiofrequency (RF) circuits to control the LED depletion zone, it could achieve an emission of optical pulses appropriat to the electrical pulses in the LED excitation to generate single photons. Nevertheless, the switching circuits for the LED control fail when the time of commutation is under 10ns, which then provokes a non-desired photon emission. This experiment shows that a controlled LED can generate a single photon.
