Journal ArticleDOI
Observation of the coupled exciton-photon mode splitting in a semiconductor quantum microcavity.
TL;DR: The spectral response of a monolithic semiconductor quantum microcavity with quantum wells as the active medium displays mode splitting when the quantum wells and the optical cavity are in resonance.
Journal ArticleDOI
Efficient carrier relaxation mechanism in ingaas/gaas self-assembled quantum dots based on the existence of continuum states
TL;DR: In this article, a comparison of near-field and far-field photoluminescence excitation (PLE) spectra gives new insight into the carrier relaxation process in InGaAs/GaAs self-assembled quantum dots.
Journal ArticleDOI
Over 1.5 μm light emission from InAs quantum dots embedded in InGaAs strain-reducing layer grown by metalorganic chemical vapor deposition
TL;DR: In this article, the authors demonstrated the 1.52 μm light emission at room temperature from self-assembled InAs quantum dots embedded in the In0.45Ga0.55As strain-reducing layer.
Journal ArticleDOI

Denis Guimard,Ryo Morihara,Damien Bordel,Katsuaki Tanabe,Yuki Wakayama,Masao Nishioka,Yasuhiko Arakawa +6 more
TL;DR: In this article, the fabrication of InAs/GaAs quantum dot solar cells (QDSCs) with enhanced photocurrent and no degradation in open circuit voltage (VOC) compared to a solar cell grown without QDs and composed solely of wetting layers.
Journal ArticleDOI
Coupling of quantum-dot light emission with a three-dimensional photonic-crystal nanocavity
TL;DR: In this paper, the first demonstration of the coupling of fully confined electrons and photons using a combination of three-dimensional photonic crystal nanocavities and quantum dots was reported.
