Abstract
We demonstrate a record low threshold current of 190 muA in a microcav ity surface-emitting laser with a 5-mum-diameter airpost, in pulsed op eration at room temperature with no heat sink. This low threshold curr ent is attributed to high-quality epitaxial layers and a dry-etched sm ooth sidewall.
