Micropillar cavity lasers demonstrate operation up to 255 K. At this temperature, the lasing threshold and Q-factor, extracted at lasing threshold for a 4 μm diameter pillar are about 2 mW and 16800. For pillar lasers, the concept of which is based on an optical aperture, continuous-wave lasing is realized at room temperature (300 K). For a 15 μm diameter pillar with an aperture of 4 μm, single-mode lasing at 960 nm is demonstrated with a threshold power of about 12 mW and a Q-factor at threshold of 13000.
