Abstract :
The authors describe the design and the high frequency modulation characteristics of a monolithic optoelectronic switch integrating a vertical-cavity surface-emitting laser with a GaAs heterojunction bipolar transistor. Large-signal electrical-to-optical modulation at a data rate of >500 Mbit/s, and small-signal modulation with a 4 GHz bandwidth have been demonstrated
