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…
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…
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…
Bidirectional photon extraction from an epitaxially grown semiconductor quantum dot sandwiched by single mode optical fibers
H. Sasakura, X. Liu, S. Odashima +3
Fiber-based bidirectional photon extraction from nanoscale emitters and photon antibunching behavior between two outputs of two single mode optical fibers are experimentally demons…
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…
Telecommunication band InAs quantum dots and dashes embedded in different barrier materials
Nahid A Jahan, Claus Hermannstädter, Jae-Hoon Huh +8
We investigate the long wavelength (1.2 to 1.55 micro-m) photoluminescence of high-density InAs quantum dots and dashes, which were grown on InP substrates. We analyze the temperat…
