Abstract
We demonstrate a record low threshold current of 190 µA in a microcavity surface-emitting laser with a 5-µm-diameter airpost, in pulsed operation at room temperature with no heat sink. This low threshold current is attributed to high-quality epitaxial layers and a dry-etched smooth sidewall.Keywords
