Abstract
Stimulated emission of optically pumped GaAs/AlAs quantum wires directly grown on (311)A‐oriented GaAs substrates has been observed at 77 K and room temperature. A significant reduction of the threshold excitation energy density for stimulated emission at room temperature could be measured in comparison to a two‐dimensional reference sample as well as a reduction of the temperature sensitivity of the threshold.Keywords
