Quantum Dot Microlasers

Not Accessible

Abstract

Laser emission from a low number of InGaAs quantum dots embedded in optically and electrically pumped high-Q micropillar laser structures will be presented. The talk will focus on the demonstration of high-β low threshold lasing with threshold currents below 10µA and single quantum dot controlled gain modulation under optical excitation.
