Journal ArticleDOI
Subnatural linewidth single photons from a quantum dot.
TL;DR: This work operates in the small Rabi frequency limit of resonance fluorescence--the Heitler regime--to generate subnatural linewidth and high-coherence quantum light from a single quantum dot.
Journal ArticleDOI
Confluence of resonant laser excitation and bidirectional quantum-dot nuclear-spin polarization

TL;DR: In this paper, it was shown that for a wide range of experimental parameters it is impossible to isolate elementary quantum-dot excitations from a strong influence of nuclear spins; the absorption lineshapes at magnetic fields exceeding 1 T indicate that the nuclear spins get polarized by an amount that ensures locking of the quantum dot resonance to the incident laser frequency, allowing the combined electron-nuclear-spin system to track the changes in laser frequency dynamically on both sides of the resonance.
Journal ArticleDOI
Observation of spin-dependent quantum jumps via quantum dot resonance fluorescence
A. N. Vamivakas,Chao-Yang Lu,Chao-Yang Lu,Clemens Matthiesen,Yi Zhao,Yi Zhao,S. Fält,Antonio Badolato,Mete Atatüre +8 more
TL;DR: The quantum dot molecule, unlike its single quantum dot counterpart, allows separate and independent optical transitions for state preparation, manipulation and measurement, avoiding the dilemma of relying on the same transition to address the spin state of an electron.
Journal ArticleDOI
Strong extinction of a far-field laser beam by a single quantum dot.
A. N. Vamivakas,Mete Atatüre,Jan Dreiser,S. T. Yilmaz,Antonio Badolato,Anna K. Swan,Bennett B. Goldberg,A. Imamoǧlu, ,‡ and,M.S. Unlu +8 more
TL;DR: This contrast level enables us to report for the first time resonant laser transmission spectroscopy on a single InAs/GaAs quantum dot without the need for phase-sensitive lock-in detection.
Journal ArticleDOI
Integrated nanophotonics based on nanowire plasmons and atomically thin material
TL;DR: In this paper, the authors demonstrate a primitive nanophotonic integrated circuit element composed of a single silver nanowire and single-layer molybdenum disulfide (MoS2) flake.
