Abstract:

We present photoluminescence studies of the molecular neutral biexciton-exciton spectra of individual vertically stacked InAsGaAs quantum dot pairs. We tune either the hole or the electron levels of the two dots into tunneling resonances. The spectra are described well within a few-level, few-particle molecular model. Their properties can be modified broadly by an electric field and by structural design, which makes them highly attractive for controlling nonlinear optical properties.
