Efficient method of designing optically-pumped vertical external cavity surface emitting lasers having equally excited quantum wells
Efficient method optically-pumped vertical external cavity surface emitting lasers equally excited quantum wells Optics
2012/4/20
Even distribution of carriers allows to maximize optical gain of the Optically-Pumped Vertical External Cavity Surface Emitting Laser. In this paper we show how to distribute the quantum wells and blo...
Strain-tuning of quantum dot optical transitions via laser-induced surface defects
Strain-tuning quantum dot optical transitions laser-induced surface defects
2011/8/17
Abstract: We discuss the fine-tuning of the optical properties of self-assembled quantum dots by the strain perturbation introduced by laser-induced surface defects. We show experimentally that the qu...
Effects of Fermi-surface shrinking on the optical sum rule in pnictides
Effects of Fermi-surface optical sum rule in pnictides
2010/11/25
In this paper we investigate the effects of the band shifts induced by the interband spin-fluctuation coupling on the optical sum rule in pnictides. We show that, despite the shrinking of the Fermi su...
