Abstract
The first measurements of the spontaneous emission coupling efficiency (/spl beta/) for electrically pumped microcavity lasers with transverse photon confinement are reported. The influence of scattering losses and carrier diffusion on microcavity lasers is investigated, A /spl beta/ of 0.01 is measured at 126 K in a 3-μm diameter device with optimal gain-cavity detuning.
