Abstract :
Summary form only given. The multiquantum-well structure was grown by metal organic vapor phase epitaxy (MOVPE) with InGaAs well layers (30 A thickness) and commensurated 1.24-/spl mu/m InGaAsP-barrier layers (100 A thickness). The semiconducting InP was used for the current blocking layer. The spontaneous emission from the side-wall was measured with optical-multichannel analyser. The gain was calculated from the spontaneous emission spectra.
