We report the first successful room-temperature CW operation of GalnAs/AllnAs multiquantum-well (MQW) injection lasers fabricated by molecular beam epitaxy (MBE). The emitting wavelength and threshold current were 1.57 μm and 530 mA, respectively, for an SiN-defined stripe laser with a 12 μm-wide, 600 μm-long cavity.
