The performances of (InAs)1/(GaAS)2 short-period superlattice strained single-quantum-well laser on GaAs substrate

The short-period superlattice (SPS) strained laser, which has a 1.07 micrometer lasing wavelength and a 130 A per centimeter squared threshold current density, is ideal to develop long wavelength lasers. The SPS laser, which does not alter the characteristic temperature of the long wavelength laser, possesses a SPS active layer, comprising InAs and GaAs.
