Summary form only given. One basic information in light-matter interaction is the homogeneous line broadening of an optical transition, inversely proportional to its dephasing time. In this work we study the homogeneous broadening in InGaAs/GaAs and in CdSe/ZnSe quantum dots by measuring both decoherence times and lineshapes. We use time-resolved four-wave mixing on an inhomogeneously broadened dot ensemble, and single-dot ...

Summary form only given. One basic information in light-matter interaction is the homogeneous line broadening of an optical transition, inversely proportional to its dephasing time. In this work we study the homogeneous broadening in InGaAs/GaAs and in CdSe/ZnSe quantum dots by measuring both decoherence times and lineshapes. We use time-resolved four-wave mixing on an inhomogeneously broadened dot ensemble, and single-dot photoluminescence spectroscopy.
In this study we perform a detailed investigation of the ultrafast processes which govern the intradot recovery dynamics of a QD InAs/GaAs structure under reverse bias condition by means of the single and two colour pump-probe technique. By studying the GS and ES recoveries as a function of reverse bias voltage and fitting the experimental results with a simple rate equation model for the intradot carrier dynamics we have illustrated the dominance of Auger mediated recovery when the ES is initially populated while phonon mediated recovery dominates for the GS case. This provides opportunities for the design of the next generation of electro-absorbing devices based on QD materials.
The paper presents Forster-type resonance energy transfer (FRET)-mediated light-harvesting of CdSe quantum dots for Atto Rhodamine 12 dye molecules using selective excitation wavelengths and achieved up to 4-fold enhancement of the Atto emission. Organic CdSe quantum dots are synthesized using hot injection method, and are emitting at 584 nm with a quantum yield of 31% that are carefully selected to spectrally match the absorption band of the acceptor dye molecules. It is shown that the strong lifetime modifications of the donor and acceptor molecules is the result of light-harvesting FRET, which will be important for bio-labelling.
This work presents a synthesis technique for implementing totally symmetric Boolean functions around quantum-dot cellular automata (QCA). The basic units of the design are the majority voter (majority gates) and and-or-inverter (AOI). The synthesis of a unate symmetric function is realized with majority gates only. Whereas, the general symmetric functions are realized, following the unate decomposition method, with AOI. The efficiency of proposed synthesis technique is compared with that of conventional CMOS-based designs. The simulation of benchmark functions confirms that the proposed technique results in better designs than that of CMOS based designs
Quantum dots offer new and promising possibilities for device applications in the optical communication 1.3 mum wavelength range. This paper investigates theoretically, the nonlinear optics of QD, in the continuous wave regime, of thin and thick quantum dot samples to have information on transmission properties, saturation parameter, self-lensing and nonlinear refractive index change. The quantum dot material parameters used in the simulation are typical for the ones grown by Innolume. They are made of 10 layers of InAs quantum dots inside GaInAs quantum wells with size and composition of the dots such that the peak of the emission is around 1280 nm. The saturation is shown to follow a behavior in between one for dominantly homogeneously and inhomogeneously broadened medium.
A strained-modified, single-band, constant-potential three-dimensional model was applied to study the dependence of electronic states of InAs/GaAs quantum dots (QDs) of different shapes and sizes. The energy trends decrease monotonously with increasing QD size (i.e. E~size<sup>-gamma</sup>) but exhibit an optimum value under aspect ratio variation. The energy dependency gamma for volume is significantly different from that for base length and height. The ground state energy for broad tip is always lower than that of narrow tip. This study allows for effective QD bandgap engineering so as to fulfil specific requirements of different QD devices
