Abstract :
Summary form only given. In summary, we have measured the thermal impedance of unmounted InGaAs QW vertical-cavity lasers. The time constant of the thermal chirp for laser elements is in the order of a few microseconds and increases with device diameter. The varying device temperature should be considered as a source of pattern effects in datacom applications.
