Abstract
We find laser emission of a (GaIn)(NAs)/GaAs VCSEL with picosecond dynamics from 30 up to 388 K. The measured band-gap shift of (GaIn)(NAs) is compara tively small. Theoretically predicted gain spectra at high densities are br oad. We conclude that the combination of both effects leads to the VCSEL op eration in such a broad temperature regime.
