  We discuss the optical response of a quantum molecule under the action of two
lasers fields. Using a realistic model and parameters, we map the physical
conditions to find three different phenomena reported in the literature: the
tunneling induced transparency, the formation of Autler-Townes doublets, and
the creation of a Mollow-like triplet. We found that the electron tunneling
between quantum dots is the responsible for the different optical regime. Our
results not only explain the experimental results in the literature but also
give insights for future experiments and applications in optics using quantum
dots molecules.
