ABSTRACT:
An optically pumped semiconductor laser comprises multiple asymmetric quantum well structures. Using the structures described herein, the selection rules for additional optical transitions can be made possible and three or four level lasers can be obtained. A population inversion can be achieved by optical pumping for lasing for those not allowed in a simple quantum well.
