All-semiconductor nanolasers on silicon

We realize room-temperature operation of nanolasers using helically-propagating modes supported by InGaAs nanopillars grown on silicon. These cavity modes provide strong optical confinement and feedback despite low index contrast between the nanopillar and silicon substrate.
