30th International Conference on the Physics of Semiconductors, 2010-07-25/07-30, Seoul (KR), DOI: 10.1063/1.3666694, pp.955-956, 2011 Abstract:
We present the differential photocurrent (DPC) measurements made on set of identical (Al)InGaP red emitting lasers under pressures up to 2GPa. 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. Keywords:
