Our studies reveal that mounting‐induced strains play an important role in the quantitative description of these LDs. We determine their influence on the laser wave‐length tuning by hydrostatic pressure. Keywords:Laser diodes, III-V semiconductors, Heterojunctions, Hydrostatics, Laser theory Affiliations:

We find that the strains applied by the submount change the pressure tuning rate from 80meV/GPa for the samples mounted on compressibility matched submounts down to about 20–50meV/GPa for the ones mounted on hard A1N or diamond submounts. The findings are discussed with the help of finite element (FE) calculations of the strains in the active layers.
