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.
