Large spontaneous emission enhancement in InAs quantum dots coupled to microdisk whispering gallery modes

Measuring the enhancement of spontaneous emission decay rates of quantum dot emission coupled to microcavity modes is typically hampered by variable coupling of the quantum dot emission. This is particularly evident in the microdisk cavity since the whispering gallery modes are localized near the disk edge, while quantum dot emitters are typically uniformily distributed throughout the disk. The...

Quantum Impurity Physics in Coupled Quantum Dots

Glossary Quantum dot device: nanoscopic electronic device resembling a transistor which incorporates a quantum dot as the central active element; sometimes also called single electron transistor. A quantum dot is an extremely small puddle of electrons which can be considered as an artificial atom since the confinement of electrons leads to quantized energy levels: the electrons form orbitals mu...
