摘要：

All-monolithic, single-step grown, room-temperature, electrically-pumped vertical cavity lasers based on III-As compounds are presented with a threshold current density 570A/cm(2), a differential efficiency greater than 50% and a threshold voltage of 3V. The lasers employ three active regions, epitaxially stacked in series with Esaki junctions to increase the gain and the differential efficiency.
