| Abstract: | A technique based on optical pumping is developed to evaluate AlGaAs/GaAs/AlGaAs epitaxial layer before fabricating semiconductor laser.Photoluminescence spectrum shows that the variance ratio of GaAs and AlGaAs peak intensities is different when increasing pumping light intenties.Some propotices of laser made by this wafaer, such as threshold and emission wavelength, can be determined by using this method.The technique is simple, rapid and undestructive. |
