Paper Abstract

The understanding of failure mechanisms in InGaAs/AlGaAs 980 nm pump lasers has gained significantly in the last couple of years. Random failure reduction has been observed as a result of improved facet-passivation techniques, and improved packaging and chip technology. With todays wear-out extrapolation data and random-failure activation estimates, there is clearly outlook for operation at higher output- power levels (200 - 250 mW) than used so far at reasonably low random-failure rates and low failure-rate operation at lower power levels (e.g. 60 mW, 25 degree(s)C, towards 25 FIT?), which clearly stimulates the interest for application of 980 nm pumps in submarine applications.
