Phys. Rev. Lett. 63, 430–433 (1989)Stimulated emission in semiconductor quantum wire heterostructuresReceived 29 March 1989; published in the issue dated 24 July 1989 We report the first observation of stimulated emission in quasi-one-dimensional semiconductor quantum wires. Amplified spontaneous emission and stimulated emission spectra of the GaAs/AlGaAs quantum wires exhibit fine structure arising from transitions between lateral, one-dimensional electron and hole subbands. The observed subband separations, ∼10 meV, are consistent with the calculated ones. © 1989 The American Physical Society URL:
