For an optical transmission experiment, several GaAlAs DH-lasers from manufacturers in Japan, USA and Germany were tested with respect to their modulation performances in the Gbit/s range. It was found that most of the studied lasers could be modulated in the Gbit/s range with neglectable pattern effect. Furthermore some lasers showed a singlemode dynamic spectrum when modulated at 1.12 Gbit/s with a light pulse power output of several milliwatts. The experiment and results are discussed in this paper.
