摘要:

我们报告的控制自发发射动力学从InAsP自组装量子点发射的电信C波段和弱耦合的模式的双异质结构腔蚀刻在一个悬浮的InP膜在室温下。腔模的品质因数为44 × 10 ^3,超低模体积为1.2 λ/n)^3,在300 K时自发发射率提高了2.8倍。

英文摘要:

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 44x10^3 with an ultra-low modal volume of the order of 1.2 lambda/n)^3, inducing an enhancement of the spontaneous emission rate of up a factor of 2.8 at 300 K.
