Abstract
In this work we experimentally study dynamics of states of light- and heavy-hole excitons in a quantum well under coherent excitation of both excitonic resonances using co- and cross- linear and circular polarizations of pump and probe beams. In the parameters of excitonic resonances quantum beats are observed. Their polarization-dependent existence is used to determine the structure of states of the light- and heavy-hole exciton system by means of theoretical modelling of experimental data.
