Proof of Stimulated Emission in Silicon-Germanium

Not Accessible

Your library or personal account may give you access

Abstract

We have investigated a hexagonal Silicon-Germanium NW on top of a microstadium resonator using time resolved photoluminescence. Clear indications of fast stimulated emission from hex-SiGe are observed, showing that we approach lasing.
