Abstract
The steady state performance of vertical cavity surface emitting laser (VCSEL) structure under the influence of the
temperature are numerically investigated by using laser technology-integrated program ISETCAD simulation. In this study,
we observed that the increase in temperature causes the increase in the threshold current, the reduction of output power,
shift of the lasing wavelength, and decrease in both of the slope output efficiency and the differential quantum efficiency.
Additionally, the operating lifetime of semiconductor lasers usually decreases exponentially with temperature. Therefore it is
essential to design lasers with consistently low temperature for better reliability. All material parameters are evaluated
based on the recent literature values.
