A pillar structure above a semiconductor substrate includes a semiconductor single-quantum-dot structure. A spin injection layer is arranged above the pillar structure. A pulsed voltage is applied between the spin injection layer and the semiconductor substrate to inject a spin-polarized single-carrier from the spin injection layer into the semiconductor single-quantum-dot structure.

The polarization controllable single-photon source allows to use magnetic or electrical means to modulate the circular polarization direction of single-photon. The modulation speed by electrical mean can reach up to GHz range.
