Fiber-coupled pillar array as a highly pure and stable single-photon source
arXiv:1707.03131 · doi:10.1063/1.4995225
Abstract
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 this array is in direct contact with a fiber end surface and cooled in a liquid-He bath. Auto-correlation measurement shows that this source provides an average value of 0.0174 in the measured excitation-power range. This photon source and fiber coupling are quite rigid against external disturbances such as cooling-heating cycles and vibration, with long-term stability.
