Temperature-dependent mollow triplet spectra from a single quantum dot: Rabi frequency renormalization and sideband linewidth insensitivity

Mostrar todas las versiones(2)

We investigate temperature-dependent resonance fluorescence spectra obtained from a single self-assembled quantum dot. A decrease of the Mollow triplet sideband splitting is observed with increasing temperature, an effect we attribute to a phonon-induced renormalization of the driven dot Rabi freque...
