Abstract:

We investigated single hexagonal silicon -germanium nanowires using photoluminescence spectroscopy. We observe stimulated emission at a threshold at 0.2 mJcm-2, with a net optical gain at -294 cm-1 below the gain threshold. This puts hex-SiGe close to lasing, opening the path to a silicon-based nanolaser.
