Interplay of coupling and superradiant emmision in the optical response of a double quantum dot
arXiv:0901.0879 · doi:10.1103/PhysRevB.80.115319
Abstract
We study theoretically the optical response of a double quantum dot structure to an ultrafast optical excitation. We show that the interplay of a specific type of coupling between the dots and their collective interaction with the radiative environment leads to very characteristic features in the time-resolved luminescence as well as in the absorption spectrum of the system. For a sufficiently strong coupling, these effects survive even if the transition energy mismatch between the two dots exceeds by far the emission linewidth.
