Abstract
An entangled-photon pair emitting device according to an embodiment of the inventive concept includes a piezoelectric structure having a first surface and a second surface, which face each other, wherein the piezoelectric structure includes an opening passing through the piezoelectric structure from the first surface to the second surface, a stress transfer medium that fills the opening, a light source emitting part disposed on the stress transfer medium, an upper electrode disposed on the first surface of the piezoelectric structure, and a lower electrode disposed on the second surface of the piezoelectric structure. Here, the light source emitting part includes a semiconductor thin-film and a quantum dot in the semiconductor thin-film.
