Strain effects in quantum wells have been intensively investigated for applications to semiconductor lasers, photodetectors and electronic devices such as pseudomorphic high electronic mobility transistors. High quantum efficiency, high power (70 mW CW and 180 mW pulsed operation), modulation-doped In0.8Ga0.2As strained-layer (compression) quantum-well lasers emitting at 1.5 um wavelength have been reported. A record high power output (206 mW CW) strained-layer InGaAs/InP quantum-well laser emitting at 1.48 to 1.51 um using the effects of tension strain has been demonstrated. A very low threshold (92 A/cm2) strained-layer quantum-well laser at 1.6 um has also been obtained.
