Fiber-coupled pillar array as a highly pure and stable single-photon source
Satoru Odashima, Hirotaka Sasakura, Hideaki Nakajima +1
A highly pure and stable single-photon source is prepared that comprises a well-designed pillar array in which each pillar contains only a few InAs quantum dots. A nano-pillar in t…
Nonlocal biphoton generation in Werner state from a single semiconductor quantum dot
H. Kumano, H. Nakajima, T. Kuroda +3
We demonstrate Werner-like polarization-entangled state generation disapproving local hidden variable theory from a single semiconductor quantum dot. By exploiting tomographic anal…
Two-photon interference and coherent control of single InAs quantum dot emissions in an Ag-embedded structure
X. Liu, H. Kumano, H. Nakajima +4
We have recently reported the successful fabrication of bright single-photon sources based on Ag-embedded nanocone structures that incorporate InAs quantum dots. The source had a p…
Vanishing fine structure splittings in telecom wavelength quantum dots grown on (111)A surfaces by droplet epitaxy
X. Liu, N. Ha, H. Nakajima +7
The emission cascade of a single quantum dot is a promising source of entangled photons. A prerequisite for this source is the use of a symmetric dot analogous to an atom in a vacu…
Symmetric quantum dots as efficient sources of highly entangled photons
T. Kuroda, T. Mano, N. Ha +10
An ideal source of entangled photon pairs combines the perfect symmetry of an atom with the convenient electrical trigger of light sources based on semiconductor quantum dots. We c…
Anomalous dip observed in intensity autocorrelation function as an inherent nature of single-photon emitters
Hideaki Nakajima, Hidekazu Kumano, Hitoshi Iijima +1
We report the observation of an anomalous antibunching dip in intensity autocorrelation function with photon correlation measurements on a single-photon emitter (SPE). We show that…
