摘要：
Temperature dependence of 980-nin vertical-cavity surface-emitting laser (VCSEL) dynamics is reported. Resonance frequency and damping factor of a 7-pm active diameter laser have been measured using noise spectra. The primary cause of reduced bandwidth with increasing temperature was reduced photon density. Differential gain is relatively constant for temperatures from 10 degrees C to 70 degrees C, and damping analysis showed there was also no significant change in K-factor as a function of temperature.
