Abstract

Recent advances made in our laboratory toward performance optimization of (A1)GaAs quantum well lasers are described. Topics to he covered include: laser reliability for broad-area devices emitting less than 300mW and its relation to the epitaxial structure and operating current density; parametric crystal growth studies and the implications for device efficiency; realization of 57% cw power conversion efficiency in an oxide-defined device; progress in dry-etching technology including array fabrication and development of device-quality laser facets suitable for integration. Finally, work in the high-power regime (>5 Watt) will be discussed. This includes broad-area single-emitter lasers emitting 6W cw.
