文摘
- •
The resonance fluorescence spectrum from triple quantum dot molecules is investigated for the first time.
- •
The resonance fluorescence spectrum is controlled by the tunneling coupling rather than the laser fields.
- •
Some interesting features such as controllable triple narrow peaks are obtained.
- •
The results can be interpreted well in the dressed state picture generated by tunneling.
- •
The tunneling coupling between the quantum dots can simulate spontaneous generated coherence (SGC).
