Strained AlGaInAs/AlGaAs quantum wells and quantum-well lasersgrown by molecular beam epitaxy

Suitable growth conditions for strained AlGaInAs grown on GaAs substrates by molecular beam epitaxy (MBE) are presented, and strained layer multiple quantum well AlGaInAs lasers grown by MBE are demonstrated. Low-temperature photoluminescence was used to characterize quantum wells grown at different temperatures with different Al, Ga, and In compositions to establish growth parameters
