We have demonstrated highly pure single-photon emissions from an InAs/InP quantum dot
at the wavelength of 1.5 μm. By applying quasi-resonant excitation, one exciton is
deterministically generated in an excited state, which then relaxes to the exciton ground
state before recombining to emit a single photon. The photon-correlation function of the
emission from the exciton ground state exhibits a record g (2)(0) value of (4.4±0.2)× 10− 4
measured using high-performance super-conducting single-photon detectors, without any …
