Abstract
This paper describes the improvements in quality of LPE wafers and in photo-electric cheracteristics of lasers by elaborate LPE and photoetching processes
with the lowest threshold current of 17 mA
single facet external differential quantum efficiency of 25%
maximum CW lasing temperature of 130℃
and the maximum output power of more than 40 mW. The reliability of lasers is enhanced by adopting PbSn welder and the modified manufacturing process. The lifetime of lasers is MTTF 25℃=2.6×10
