Partial suppression of the spectral diffusion of quantum dot (QD) excitons tuned to resonance of a nano-photonic cavity is reported. The suppression is caused by the Purcell enhancement of the QD-exciton recombination rate, which alters the rate of chargin ...

Narrow inhomogeneous broadening of V-groove quantum wires grown on vicinal substrates

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Daniel Oberli, Pascal Gallo, Nicolas Moret

Significant reduction in inhomogeneous broadening of GaAs/AlGaAs V- groove quantum wires (QWRs) is achieved by growing them on vicinal (001) GaAs substrates misaligned by several degrees with respect to the [1 (1) over bar0] groove direction. Low temperatu ...
