Time-resolved and polarization-resolved measurements are preformed on InAs/GaAs quantum dots by means of time-resolved differential reflection spectroscopy. With this technique, the polarization anisotropy of the absorption bleaching in a quantum dot is measured. The excitation density dependent measurements of the bleaching magnitude, show a strong polarization dependence, which corresponds to linear dichroism. Dichroism with a magnitude of 1.3 is observed, governed by strain within the sample.
