Thermal Performance of 940 nm AlGaAs-Based VCSELs Grown on Germanium
VCSEL thermal resistances are determined from power-current-voltage-wavelength measurements performed on nominally identical epitaxial structures grown on Ge and GaAs substrates. We show that the effective thermal conductivity of the VCSEL is increased when grown on Ge substrates.
