Damping of exciton Rabi rotations by acoustic phonons in optically excited InGaAs/GaAs quantum dots. by Ramsay, A, Gopal, A, Gauger, E, Nazir, A, Lovett, B, Fox, A, Skolnick, MS

“…We report experimental evidence identifying acoustic phonons as the principal source of the excitation-induced-dephasing (EID) responsible for the intensity damping of quantum dot excitonic Rabi rotations. The rate of EID is extracted from temperature dependent Rabi rotation measurements of the ground-state excitonic transition, and is found to be in close quantitative agreement with an acoustic-phonon model.…”
