Room temperature spontaneous emission enhancement from quantum dots in photonic crystal slab cavities in the telecommunications C band

We report on the control of the spontaneous emission dynamics from InAsP self-assembled quantum dots emitting in the telecommunications C band and weakly coupled to the mode of a double heterostructure cavity etched on a suspended InP membrane at room temperature. The quality factor of the cavity mo...

Zusammenfassung:We report on the control of the spontaneous emission dynamics from InAsP self-assembled quantum dots emitting in the telecommunications C band and weakly coupled to the mode of a double heterostructure cavity etched on a suspended InP membrane at room temperature. The quality factor of the cavity mode is 44 × 10 3 with an ultralow modal volume of the order of 1.2 ( λ / n ) 3 , inducing an enhancement in the spontaneous emission rate of up a factor of 2.8 at 300 K.
