Abstract
A fabrication process for laterally index-confined planar microcavity lasers is given that results in continuous-wave thresholds as low as 5 9 mu A for a properly tuned cavity (T = 250 K). Characterization of th e spontaneous emission mode shows that the lateral confinement, when r educed to the mode size expected for the planar cavity, appears to inc rease the spontaneous emission coupling to the lasing mode.
