Pseudomorphic InGaAs lasers with cw operating lifetimes exceeding 5000 h are reported for the first time. The device structure, grown by low-pressure metalorganic chemical vapor deposition, incorporates a single In0.37Ga0.63As strained-layer quantum well in a GaAs/AlGaAs graded-index separate confinement heterostructure. These devices are remarkable for their immunity to sudden failure and for their (gradual) degradation rates which are comparable to the best GaAs lasers.

    For InGaN laser diodes with emission wavelengths longer than 435 nm, the threshold current density usually increases with the number of InGaN well layers. This phenomenon could be attributed to the dissociation of the high indium content InGaN well layer at a high growth temperature of 750 °C...

    Whereas laser emission at 1.55 μm is difficult to realize using type-I InGaAsN quantum wells grown on GaAs, we show that it can be achieved with far fewer restrictions on the growth by employing type-II (In)GaAsN/GaAsSb/(In)GaAsN/GaAs structures having a “W” band alignment. We use...
