摘要：

Distribution of electronic states inside ridge quantum-wire (QWR) laser cavity was investigated using spatially and spectrally resolved top-view photoluminescence (PL) imaging method. PL inhomogeneity in QWR has shown that the electronic states were perturbed by the fluctuation of vertical thickness in the scale of similar to nm, while the optical waveguide was not. The PL images of QWR were traced up to the lasing condition to examine the lasing origin. (C) 1999 American Institute of Physics. [S0003-6951(99)00541-0].
