Time- and spectrally-resolved four-wave mixing in single CdTe/ZnTe quantum dots

Abstract:

We present transient four-wave mixing experiments on individual excitonic transitions in self-assembled CdTe/ZnTe quantum dots. Using a two-dimensional femtosecond spectroscopy and heterodyne detection of the nonlinear signal we study the dephasing and mutual coherent coupling of single quantum dot states. For the homogeneous linewidth of the zero-phonon line (ZPL) values of 0.06-0.1 meV (T2 =13-20 ps) are measured, and a ZPL weight in the total line shape of Z=0.9 at T=7 K is estimated. We o...
