Abstract
We present a novel approach to determine the thermal resistance and the internal temperature of vertical-cavity surface-emitting lasers (VCSELs) based on easily accessible laser parameters. The described method does not use any empirical parameters or pulsed measurements that are often mentioned in literature. We explain how to determine the thermal resistance and show the computation of the internal temperature for any operation point. Furthermore the data evaluation can be used for characteristic parameter extraction that enables us to establish an isothermal and temperature-dependent modeling of the VCSEL operation curves.
