Spontaneous emission control of single quantum dots by electromechanical tuning of a photonic crystal cavity
Spontaneous emission control of single quantum dots by electromechanical tuning of a photonic crystal cavity
We demonstrate the control of the spontaneous emission rate of single InAs quantum dots embedded in a double-membrane photonic crystal cavity by the electromechanical tuning of the cavity resonance. Controlling the separation between the two membranes with an electrostatic field, we obtain the real-time spectral alignment of the cavity mode …
