Research Abstract

Electrically-controlled single-photon emitters were studied in this study. We designed the layer structure of the current-injected single-photon emitters by considering the electronic structures of a InAs/InP quantum dot which emits telecommunication-band single-photons. Wavelength tunable single-photon emitter was successfully demonstrated by using quantum-confined Stark shift of the exciton energy in the biased quantum dot.
