Laser Spectroscopy and Quantum Optics in GaAs and InAs Semiconductor Quantum Dots

摘要: Abstract This chapter reviews primarily the evolution of understanding coherent optical interactions and spectroscopy in semiconductor quantum dots. The work begins by a brief review dominance complex many-body higher dimensional materials then proceeds to examine behavior knowledge extracted using frequency domain techniques, which has provided considerable insight into physics these systems. results show that confinement suppresses kind seen bulk material allows interaction be well described two or few state energy-level diagrams master equations density matrix. Numerous examples classical atomic are reviewed including Rabi oscillations, population trapping, Mollow absorption spectrum. also discusses how structures can used as platform for possible applications information sciences. Finally, concludes examining role hyperfine interaction. Unlike systems with one nucleus, dot excitons involve order 10 4 nuclei. is origin decoherence spin doublet ground negatively charged dot. However, studies have shown an unexpected coupling between exciton nuclei leads freezing nuclear fluctuations.
