Abstract

We demonstrate low-threshold lasing at 4 K in optically pumped hemispherical In_0.2Ga_0.8As single-quantum-well microcavities. The incident threshold pump power density is 11 kW/cm² corresponding to an absorbed power density of about 320 W/cm², and the measured spontaneous emission factor β is about 0.01.
