Internal loss is a key internal parameter for high power 1060-nm InGaAs/A1GaAs semiconductor laser. In this paper, we discuss the origin of internal loss of 1060-nm InGaAs/GaAs quantum welt (QW) AIGaAs separate conf...
Compared with the conventional strained quantum well, the InGaAs/GaAsP strain compensated quantum well (SCQW) has better optical properties, as the well layer and the barrier layer lattice mismatch with each other whi...
