Abstract
Coherent dynamics measured by time-resolvedfour-wave mixing is compared to incoherent population dynamicsmeasured by differential transmission spectroscopy on the ground-state transition at room temperature of two types of InAs-based quantum dots with different confinement energies. The measurements are performed with heterodyne detection on quantum-dot active wave guides to enhance the light–matter interaction length. An elastic nature of the measured dephasing is revealed which is independent of the dot energy level scheme.
