The effect of group V/III flux ratio ..gamma.. on the reliability of GaAs/Al/sub 0.3/Ga/sub 0.7/As double-heterostructure lasers grown by molecular beam epitaxy at 720 /sup 0/C has been studied. The threshold current does not change with ..gamma... By contrast, the degradation rate strongly depends on ..gamma.. and it takes a minimum at ..gamma..approx.3 where the photoluminescence intensity of the Al/sub 0.3/Ga/sub 0.7/As cladding layer is maximum. In the case of ..gamma..approx.3, the degradation rate is lower than that of lasers grown by liquid phase epitaxy.
