We demonstrate laser emission by photopumping at room temperature from a distributed feedback structure for a surface-emitting laser constructed by alternating growths of a GaAs/AlGaAs multiquantum well and an Al0.7Ga0.3As layer using molecular-beam epitaxy. A threshold photoexcitation intensity lower than 3.1×105 W/cm2, a 34-nm longitudinal mode spacing, and a 2.3-nm peak width of the laser emission were observed for the 6-μm-thick multilayer.
