Journal ArticleDOI
Red-Emitting Semiconductor Quantum Dot Lasers
Simon Fafard,Karin Hinzer,Sylvain Raymond,M. Dion,John P. McCaffrey,Yan Feng,Sylvain Charbonneau +6 more
TL;DR: Red-emitting, self-assembled QDs of highly strained InAlAs have been grown by molecular beam epitaxy on a GaAs substrate to demonstrate the good size distribution and high gain in these high-quality QDs.
Journal ArticleDOI
Photonic integrated circuits fabricated using ion implantation
Sylvain Charbonneau,Emil S. Koteles,Philip J. Poole,Jian-Jun He,G. C. Aers,J.E. Haysom,Margaret Buchanan,Yan Feng,A. Delage,Fang Yang,Michael Davies,R. D. Goldberg,P. G. Piva,Ian V. Mitchell +13 more
TL;DR: In this paper, a technique based on ion implantation-induced QW intermixing was developed to enhance the QWI rate in selected areas of a wafer, which offers the prospect of a powerful and simple fabrication route for the integration of discrete optoelectronic devices and for forming photonic integrated circuits.
Journal ArticleDOI
Lasing in quantum-dot ensembles with sharp adjustable electronic shells
TL;DR: In this article, the authors used shape-engineered stacks of self-aligned QDs with improved uniformity to increase the gain in the active region of the laser diodes.
Journal ArticleDOI
Band-gap tuning of InGaAs/InGaAsP/InP laser using high energy ion implantation
Sylvain Charbonneau,Philip J. Poole,Yan Feng,G. C. Aers,M. Dion,Michael Davies,R. D. Goldberg,Ian V. Mitchell +7 more
TL;DR: In this paper, the authors used ion-induced quantum well intermixing using broad area, high energy (1 MeV P+) ion implantation to tune the emission wavelength of an InGaAs/InGaAsP/InP multiple quantum well (MQW) laser operating at 1.5 μm.
Journal ArticleDOI
Collapse of the Zeeman gap in quantum dots due to electronic correlations
TL;DR: In this article, the authors present results of calculations and lateral magnetotunneling experiments on small quantum dots in the few-electron regime, showing that a systematic oscillation of the chemical potential of the droplet as a function of the magnetic field correlates with oscillations in the current amplitude.
