Paper Abstract

MOVPE grown InAlGaAs SQW lasers for approximately 730 nm have been optimized for low oxygen incorporation, where diethylether associated with trimethylindium (TMI) provides the dominant oxygen impurity. An ether free preparative route to TMI, together with a large indium fraction for the SQW has provided device lifetimes of approximately 2000 hours when operating at 1.2 W and 743 nm.
