Abstract :
Summary form only given. The VCSELs of this work are based on an implanted-aperture, index-guided, lateral current injected, top dielectric mirror GaAs quantum well 850 nm design. The thermal simulation employs quasi-three dimensional finite difference analysis to calculate the temperature, thermal resistance and the rise time of temperature at a fixed bias to calculate the nonuniform heat source distribution.
