Abstract

The room-temperature dephasing in InAs/GaAs self-assembled quantum dots is measured using two independent methods: spectal-hole burning and four-wave mixing. Dephasing times weakly dependent on the excitation density are found, with a low density value of 290±80 fs from spectal-hole burning and of 260±20 fs from four-wave mixing.
