A combination of a single quantum emitter (a semiconductor quantum dot) with a semiconductor optical nanocavity has been employed to demonstrate devices ranging from optical switches and modulators controlled with sub-fJ energies, to quantum sources.

Quantum dots (QDs) coupled to photonic crystal cavities are interesting both as a testbed for fundamental cavity quantum electrodynamics (CQED) experiments, as well as nano-scale devices for optical quantum and classical information processing. In ad

A photonic crystal cavity with a strongly coupled quantum dot is coherently driven using short laser pulses. Depending on the driving frequency, photon blockade or photon induced tunneling is observed. These nonlinear phenomena at single photon level

Recent years have shown tremendous progress in the fabrication of single photon sources (SPS) based on quantum dots (QDs) embedded in semiconductor micro and nanocavities which are of interest for applications in quantum information science. Here we

We coherently probe a quantum dot that is strongly coupled to a photonic crystal nano-cavity by scattering of a resonant laser beam. The coupled systempsilas response is highly nonlinear as the quantum dot saturation with nearly one photon per cavity

Summary form only given. We discuss the growth and optical properties of InGaAs/GaAs self assembled quantum posts (QPs). The MBE grown QP is formed of a seed quantum dot (QD) connected to a short quantum wire and is capped by another QD. The QP lengt

A single photon source is demonstrated using a novel oxide-apertured micropillar cavity embedded with InGaAs quantum dots. A bright 80 MHz count rate is enabled by the Purcell effect and charge-tuning of the quantum dots.

We discuss a novel optical assessment of dry etch damage, with high degree of sensitivity, by measuring the microdisk resonator Q. Effects of etch gas composition, bias power and sample preparation (resist reflow) were examined.

We demonstrate characteristics of InAs/GaAs quantum-dot photonic-crystal lasers with high spontaneous emission coupling efficiencies and soft-turn-on behaviors. Pronounced bunching signals subside with the increase of pumping, revealing the onset of

Using path-integral quantum Monte Carlo, the energy of charged excitons and biexcitons is calculated for various quantum dot quantization energies. Results show good agreement with measured values in contrast with a first-order perturbation approach.
