Advanced micropillar cavities: room-temperature operation of microlasers

Abstract

High-quality micropillar cavities were grown using molecular-beam epitaxy. Stable continuous-wave lasing at room-temperature was demonstrated for microlasers with semiconductor and hybrid output mirrors. At 300 K, single-mode lasing was demonstrated for micropillars with a diameter of 5 $\mu$m at a wavelength of 960 nm, with a minimum lasing threshold of 1.2 mW and a bare quality-factor exceeding 8000.
