Near and Mid Infrared Spectroscopy of InGaAs/GaAs Quantum Dot Structures
Abstract
Results of a photo- and electroluminescence study of vertically coupled in(o.5)Ga?0.5)As/GaAs quantum dot structures with extended waveguide (1.24 micrometers thick) are presented. Spectra of spontaneous and stimulated near-infrared (lambda about 1 micrometer) emission as well as spectra of spontaneous mid-infrared (lambda about 12 micrometers) emission are obtained under optical and electrical pumping. It is shown that the observed mid-infrared emission is connected with intraband electron optical transitions in the quantum dot structtures.
