Few-Particle Effects in Nonlinear Optical Spectra of Semiconductor Quantum Dots
Published online by Cambridge University Press: 10 February 2011
Abstract
We present a density-matrix approach for the description of nonequilibrium carrier dynamics in optically excited semiconductor quantum dots, that explicitly accounts for exciton-exciton as well as exciton-carrier interactions. Within this framework, we analyze few-particle effects in the optical spectra and provide a consistent description of additional peaks appearing at high photoexcitation density. We discuss possible applications of such optical nonlinearities in future coherent-control experiments.
