Abstract

We report on room-temperature continuous-wave operation and single-mode lasing of microdisk and microring lasers with radii as small as 7 mum. The waveguide sidewall roughness was minimized by an optimized fabrication process using hydrogen silsesquioxane e-beam resist and Cl 2-CH 3-H 2 inductively coupled plasma etching. The devices show unidirectional bistability between the counterpropagating modes for radii larger than 30 mu m and a strong hybrid output polarization for radii smaller than 15 mum with a transverse-magnetic component of approximately 30%.
