Lasing from Quantum Dots Formed by Activated ALloy Spinodal Decomposition on InAs Stressors

Abstract

We demonstrate injection lasing in structures with a novel type of quantum dots (QDs) formed by activsaed spinodal decomposition on InAs stressors. At low temperatures the lasing is observed via the first exited QD exciton state with the lasing wavelength of 1.1 micrometer. With temperature increase lasing switches to higher energy states but remains up to room temperature. Simultaneous lasing via two energy states is also observed.
