Abstract
We measure a dephasing time of several hundred picoseconds at low temperature in the groundstate transition of strongly confined InGaAs quantum dots, using a highly sensitive four-wave mixing technique. Between 7 and 100 K the polarization decay has two distinct components resulting in a non-Lorentzian line shape with a lifetime-limited zero-phonon line and a broadband from elastic excitonacoustic phonon interactions.
