| Research Abstract |
We constituted a much more simple and inexpensive single photon source than conventional ones. Semiconductor nanoparticles are embedded in a thin film of polymer and one of those particles are illuminated by a laser radiation. Because of the quantum confinement effect in nanoparticles, a single nanoparticle cannot emit multiple photons at one time, i.e. this system can work as a single photon source. We have obtained more than 10 thousand photons per second in a single mode fiber and confirmed the antibunching property, which is the clear evidence for a single photon source.
