Abstract :
Summary form only given. The authors report the first successful room-temperature pulsed operation of InGaAs strained-layer multiquantum-well (SL-MQW) injection lasers grown by MOVPE (metal-organic vapor-phase epitaxy) on InP substrates in the 1.8-μm range. The threshold current density and external differential quantum efficiency of 10-μm-wide ridge waveguide lasers were 2.5 kA/cm2 and 5% for 1-mm and 400-μm-long cavities, respectively. The laser structure consists of four 35-Å-wide In0.75Ga0.25As SL-QWs separated by 65-Å-wide barrier layers of lattice-matched InGaAs. The MQW is further sandwiched between 150 nm of InGaAsP (λ=1.3 μm) and 2 μm of InP on both sides
