Long-wavelength vertical-cavity surface-emitting lasers (VCSELs) are strongly temperature sensitive. Room-temperature continuous-wave operation of those VCSELs has been achieved only recently. Here, we investigate pulsed operation of 1.55 /spl mu/m VCSELs with strain-compensated InGaAsP/InP multi quantum wells (MQWs). A comprehensive two-dimensional VCSEL model is used to investigate those temperature effects. The optical gain is obtained from kp band structure computations and it includes many-body effects. Temperature dependent loss mechanisms like Auger recombination, carrier leakage, and intervalence band absorption are considered. Careful adjustment of material parameters led to an excellent agreement with a large variety of measurements.
