Abstract

The excellent operating properties of GaAs/ GaAIAs single quantum-well (SOW) lasers are well documented¹; detailed understanding of the operating features of such lasers is, however, still lacking. We, therefore, performed an experimental and theoretical study of some of these features: (1) the optimization of quantum-well width; (2) the influence of the optical cavity in separate-confinement (SCH) and graded-index separate-confinement (GRIN-SCH) heterostructures; (3) the difference between the excellent performance of GaAs/ GaAIAs lasers and the bad performance (no lasing at room temperature) of GalnAs/lnP lasers. The various results of our study are as follows:
