Abstract

We report an 830nm high power single spatial mode DFB laser design in the AlGaAs/GaAs system that offers performance close to a Fabry-Perot design as well as manufacturing yield compatible with volume production. Single-mode power in excess of 200mW at case temperature up to 60⁰C is consistently obtained for current below 300mA. This performance level is enabled by use of an efficient, partially-corrugated design and a 2nd order grating located on the p-side. Through careful design and an optimized epitaxial re-growth on the grating, promising reliability results compatible with uncooled application are demonstrated.
