    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 measurements show that this source provides an average g((2))(0) 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. Published by AIP Publishing.

    We study the spectral diffusion in a single epitaxial InAs quantum dot placed in a silver-embedded nanocone structure. Making use of a series of stroboscopic detection of optical transitions, we demonstrate the temporal fluctuations in peak energy of photoluminescence. In particular, the photoluminescence fluctuations can be effectively suppressed by strong illumination. By analyzing the photon statistics, we find that the dot emission exhibits stable non-classical nature with the strong anti-bunching behavior after this stabilization.

    We study stable and efficient coupling of single photons generated from a quantum dot (QD) into a single-mode fiber (SMF) prepared in a fiber couple module (FCM). We propose a method to focus the objective lens to a sample surface without imaging with the help of laser reflection. By assembling all the constituents, i.e., a pair of lenses, the SMF, and the optical alignment to the QD source, we demonstrate stable single-photon count rate and a high collection efficiency of 43.5% of the photons emitted in air from the QD into the collection lens in the FCM.

    Highly pure and stable single photon source is established. Well-prepared pillar array which involve InAs QDs is directly contacted to a fiber end-surface, and cooled in a liquid He bath. Auto-correlation measurement shows that it works as a highly pure single photon source providing g((2))(0) <0.1 not only in the weak excitation case but also in the moderately strong excitation one. This photon source is quite rigid against the external disturbance such as cooling-heating cycle and vibration, with a long term stability. Such a pure and stable single photon source is quite promising to build up fiber-based quantum information technology to the actual stage.

    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 photon collection efficiency as high as 24.6%. Here, we show the results of various types of photonic characterizations of the Ag-embedded nanocone structures that confirm their versatility as regards a broad range of quantum optical applications. We measure the first-order autocorrelation function to evaluate the coherence time of emitted photons, and the second-order correlation function, which reveals the strong suppression of multiple photon generation. The high indistinguishability of emitted photons is shown by the Hong-Ou-Mandel-type two-photon interference. With quasi-resonant excitation, coherent population flopping is demonstrated through Rabi oscillations. Extremely high single-photon purity with a g((2))(0) value of 0.008 is achieved with pi-pulse quasi-resonant excitation. (C) 2014 AIP Publishing LLC.

    We have realized metal-coated semiconductor nanostructures for a stable and efficient single-photon source (SPS) and demonstrated improved single-photon extraction efficiency by the selection of metals and nanostructures. We demonstrate with finite-difference time-domain (FDTD) simulations that inclination of a pillar sidewall, which changes the structure to a nanocone, is effective in improving the photon extraction efficiency. We demonstrate how such nanocone structures with inclined sidewalls are fabricated with reactive ion etching. With the optimized design, a photon extraction efficiency to outer airside as high as similar to 97% generated from a quantum dot in a nanocone structure is simulated, which is the important step in realizing SPS on-demand operations. We have also examined the direct contact of such a metal-embedded nanocone structure with a single-mode fiber facet as a simple and practical method for preparing fiber-coupled SPS and demonstrated practical coupling efficiencies of similar to 16% with FDTD simulation.

    We report a comprehensive investigation of carrier-transfer dynamics in a single InAs quantum dot (QD) based on second-order photon correlation measurements. The experimentally obtained auto and crosscorrelation functions as well as photoluminescence intensities are successfully explained on the basis of a series of rate equations with common excitation and also single-carrier-capture/escape rates to/from a QD. This approach enables us to understand the carrier-transfer dynamics responsible for the stability of a quantum two-level system formed in a single QD under various excitation conditions. We clarify that the transition between neutral and charged excitonic states is suppressed by one order of magnitude under quasiresonant excitation.

    Fiber-based bidirectional photon detection from nanoscale emitters and photon antibunching behavior between two outputs of two single-mode fibers (SMFs) are experimentally demonstrated. Flakes containing the epitaxially grown quantum dots (QDs) are mechanically fixed by both sides with the edge faces of the SMF patch cables. The emitting photons from a single QD are directly taken out of both sides through the SMFs. Single-photon emission between two SMF outputs is confirmed by detecting nonclassical antibunching in second-order photon correlation measurements. This simple optomechanical alignment-free single-photon emitter is advantageous because of its robust stability of more than three months and low-cost fabrication.

    We have fabricated silver microcolumnar photon reflectors to enhance the photon extraction efficiency from a quantum dot. The mechanically robust planar structure is favorable to couple to optical fibers for stable and efficient single-photon sources. A high photon extraction efficiency of up to 18% is achieved. Furthermore, strong suppression of multiphoton generation is confirmed. The proposed structure is quite promising toward the implementation of practical quantum key distribution systems with dot-fiber-coupled photon sources. (C) 2013 The Japan Society of Applied Physics

    High photon-extraction efficiency is strongly required for a practical single-photon source. We succeed in fabricating metal (sliver)-embedded nanocone structure incorporating an InAs quantum dot. Efficient photon emission of similar to 200 000 photons per second is detected and single-photon emission is demonstrated using autocorrelation measurements. The photon-extraction efficiency as high as 24.6% is obtained from the structure. (C) 2013 AIP Publishing LLC. [http://dx.doi.org/10.1063/1.4801334]

    The injection of Cooper pairs into a normal medium such as a semiconductor is known as the proximity effect at the superconductor/normal interface. We confirm this injection as well as the contribution of Cooper pairs to a drastic enhancement of inter-band optical transitions in semiconductor heterostructures. In this paper we investigate and clarify the relation of internal quantum efficiencies and radiative lifetimes in Cooper-pair light emitting diodes (CP-LEDs). A quantitative description of the dynamic photon generation processes is given, and the contribution of the Cooper-pair recombination relative to normal-electron recombination in CP-LEDs is discussed in detail.

    GaSb quantum rings (QRs) of different sizes and shapes were grown by metal organic molecular beam epitaxy (MOMBE). Partially capped InAs quantum dots (QDs) grown on a GaAs buffer layer were flattened by In-flushing, followed by regrowth of GaSb which forms ring structure around the InAs seed dots. With the assistance of such an InAs/GaAs groundwork layer, the GaSb QRs exhibit a better defined shape compared to the spontaneously formed rings. First, rims of QRs develop around the boundary of the InAs/GaAs, then additional GaSb QDs grow on top of them preferentially along the [0 - 1 1] direction compared to [0 1 1]. (C) 2011 Elsevier B.V.

    A light-emitting diode (LED) in the optical-fiber communication band showed special features after replacing the n-type electrode with niobium (Nb) superconducting metal. Nb electrodes prepared on an InGaAs-based semiconductor surface formed a superconductor/semiconductor/superconductor junction, and the current-voltage characteristics exhibited both DC and AC Josephson junction properties. This was a result of the injection of electron Cooper-pairs into the n-InGaAs active layer of an LED. The drastic enhancement of the electroluminescence output observed below the Nb superconducting critical temperature, T(c), demonstrates the active role of electron Cooper-pairs in radiative recombination. Lifetime measurements of this LED and accurate evaluation of the luminescence output made it possible to estimate the radiative recombination lifetimes. A theoretical formula derived for the Cooper-pair radiative recombination accurately describes both the measured steep reduction of the radiative recombination lifetime and the observed enhancement of the internal quantum efficiency below Tc. This work will assist the development of interdisciplinary physics and new applications in superconductivity and optoelectronics. (C) 2010 The Japan Society of Applied Physics

    Electronic states of the two-orbital Hubbard model are investigated by means of the composite operator method. In addition to the transfer within the same kind of orbital, we introduce the off-diagonal transfer t', which provides the mixing of orbitals. In the t' = 0 case, the system shows the orbital selective Mott transition at U = 4. Upon adding t', the band gap goes wider. This increase of the gap originates from the crossover between the Mott-insulator and the band-insulator.

    Ga-doped ZnO thin films were prepared by RF magnetron sputtering. The effects of adding H-2 to pure Ar sputtering gas were investigated. In the case of pure Ar at 2 Pa, the resistivity is 7.45 x 10(-3) Omega cm, whereas for Ar + 1 %H-2 at 0.3 Pa, it markedly decreases to 2.52 x 10(-4) Omega cm. In this case, the carrier density and Hall mobility are 1.12 x 10(21) cm(-3) and 23.4 cm(2)/Vs, respectively. This conductive film also exhibits a transmittance of 90% within the visible-wavelength range. The addition of H-2 and the decrease in the pressure results in the fabrication of a significantly more transparent and conductive film.

    We analyze the two-orbital Hubbard model by means of the composite operator method with the aim at studying the phenomenon of orbital selective Mott transition (OSMT). The model contains an interorbital interaction LP, in addition to the usual intraorbital one U. As warming-up approximation, we use a basis of two operators only, the Hubbard operators. The analysis of the density of states at the chemical potential as a function of the ratio between the bandwidths of the two orbitals shows the clear signature of an orbital selective Mott transition as expected.

    The electronic states of the two-dimensional Hubbard model are investigated by means of a 4-pole approximation within the Composite Operator Method. In addition to the conventional Hubbard operators, we consider other two operators which come from the hierarchy of the equations of motion. These operators carry information regarding surrounding spin and charge configurations. In the study of thermodynamic quantities, such as internal energy and specific heat. our results present an excellent agreement with the data of numerical simulation. Furthermore, in the low-temperature region, they show a decrease of energy suggesting spin and charge ordering which cannot be well evaluated by the former 2-pole approximation.

    The electronic states of the two-dimensional Hubbard model are investigated by means of a 4-pole approximation within the composite operator method. In addition to the conventional Hubbard operators, we consider other two operators which come from the hierarchy of the equations of motion and carry information regarding nearest-neighbor spin and charge configurations. By means of this operatorial basis, we can study the physics related to the energy scale of J=4t(2)/U in addition to the one of U. Present results show relevant physical features, well beyond those previously obtained by means of a 2-pole approximation, such as a four-band structure with shadow bands and a quasiparticle peak at the Fermi level. The Fermi level stays pinned to the band flatness located at (pi,0)-point within a wide range of hole-doping (0 <=delta <= 0.15). A comprehensive analysis of double occupancy, internal energy, specific heat and entropy features have also been performed. All reported results are in excellent agreement with the data of numerical simulations.

    The electronic states of the Hubbard model are investigated by use of the composite operator method. In addition to the Hubbard operators, two other operators related with two-site composite excitations are included in the basis. Within the present formulation, higher-order composite excitations are reduced to the chosen operatorial basis by means of a procedure preserving the particle - hole symmetry. The positive comparison with numerical simulations for the double occupancy indicates that such approximation improves over the two-pole approximation. (C) 2003 Elsevier B. V. All rights reserved.

    We propose a theoretical approach, within the framework of the composite operator method, to include the effects of finite cluster correlations into the self-energy of strongly correlated systems. The Hubbard model is analyzed as significant example. The self-energy is rewritten in terms of two-site composite-operator propagators, which are computed by means of a two-site approximation preserving relevant symmetries (e.g., particle-hole symmetry). The involved composite operators describe charge, spin and pair nearest-neighbor correlations and the excitations related to the induced exchange coupling (J = 4t(2)/U). The procedure results in a very rich band structure going well beyond the results of the two-pole approximation. (C) 2003 Elsevier Science B.V. All rights reserved.

    Temperature and hole doping dependence of local magnetic moments induced by nonmagnetic impurities in the two-dimensional t-J model is investigated by use of a Green function method in a finite size system. Around the impurity site, areas within a radius r(s), pi r(s)(2), are magnetically distorted (r(s) = 3a-4a). With hole doping, additional holes go to the inside of magnetic regions, and magnetic regions are dispersed outside with rapidly decreasing their magnitude. At 2% impurity doping, the whole system is magnetically distorted. It is consistent with experimental results for Zn-doped high-T-c superconductors. (C) 2000 Published by Elsevier Science B.V.

    Local magnetic moments induced by a nonmagnetic impurity in the two-dimensional t-J model are investigated by use of a Green function method in a finite-size system (50x50=2500 sites). Local electron number and nearest-neighbor correlation functions are calculated self-consistently at each lattice point. A local electron number distribution shows that electrons form a bound state around an impurity site and the magnitude of the local moment is enhanced, whereas doped holes can be distributed only apart from the impurity site and destroy an antiferromagnetic spin configuration by their motion. This result is consistent with experimental results of Zn-doped high-T-c superconductors.

    The modified Kondo-Heisenberg model for high-Tc oxide superconductors and the Kondo-Heisenberg model are analysed by the composite-operator expansion method. We study the effects of short-range antiferromagnetic correlations on the density of states and related band dispersion near the Fermi level when the Heisenberg insulator is doped. A set of self-consistent equations for fermionic correlation functions are solved by a numerical calculation. It turns out that the next-to-nearest-neighbour copper spin-spin correlations on extended lattice clusters can be used to predict the width of the band crossing the Fermi level in the same experimental range. Results are compared with previous calculations and a detailed discussion is given on the approximations implemented.

    The electronic state of the 2D Hubbard model is investigated by including effects of two-site local correlation. The upper and lower Hubbard bands have a three-peak structure at half-filling. With doping of carriers, an increase of the density of states at the Fermi level is induced. The results show similar shapes of the electron spectral function to those obtained in the numerical simulation by Dagotto et al.

    A highly correlated p-d model of cuprate oxide superconductors is analyzed by use of composite operators on CuO2 dusters. A minimal set of composite operators to describe the electronic state is identified from the criterion that the order of the approximation is determined by coupling constants multiplied by the weight of their respective operators. It is shown that the intensity transfer among bands with hole doping is well described within the mean-field approximation. Effects of the nearest-neighbor spin correlation are investigated and it is shown that the band dispersions are strongly affected. By the local antiferromagnetic correlation, the band dispersion of the upper Hubbard band is flattened in the whole Brillouin zone, while that of the p dominant band near the Fermi level is flattened only around a certain region centered at the zone boundary. In the moderately doped region, the Fermi surface is consistent with a large Fermi surface.
