ABSTRACT
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 44×103 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.

    We report evidence for the existence of anticorrelation in InGaAs/GaAs self-assembled quantum dots (QDs). We found that, as a function of the spacer layer thickness, the QDs between the neighboring layers are either vertically correlated (at small spacer thickness) or anticorrelated (at larger...

    We demonstrate the spatial localization of optically active InAs quantum dots in the narrow whispering gallery mode region of a GaAs microdisk cavity. This is achieved through preferential In adatom surface diffusion on a partial cavity structure in a way that can be generalized to other optical...

    Selective formation of InAs quantum dots on the sidewalls of mesa strips along both [01-1] and [011] directions of a GaAs(100) surface is demonstrated. This result is in sharp contrast to observations on traditionally deep-patterned substrates, where quantum dots are formed on top mesas and at...

    We report on optical properties of InAs QD based mid- and far-infrared quantum dot infrared photodetectors (QDIP) in different host matrix environments.

    One of the main obstacles to coupling two quantum dots (QDs) to a single nanocavity mode in a cavity quantum electrodynamics system is the ability to independently tune the QD frequencies. We demonstrate that in a GaAs photonic crystal membrane structure with two embedded QD layers, the QD...
