Abstract
Electromagnetic induced transparency is an optical phenomenon that allows transmission of a laser beam through a dense medium by using a control laser beam. Here, we propose the use of a quantum molecule where the control laser beam is replaced by the electron tunneling between quantum dots, which can be controlled by an external electric field, opening the possibility to induce transparency and slow light with electric gates. Our results show that a transparency window appears if the tunneling strength ${T}_{e}$ and the decay rate of direct exciton ${\ensuremath{\Gamma}}_{1}$ obey the condition ${T}_{e}/{\ensuremath{\Gamma}}_{1}\ensuremath{\le}0.5$.
