Abstract :
The authors recently reported the integration of a SIBH laser and an invertible heterobipolar transistor as an emitter follower in a 600-Mb/s OEIC (optoelectronic integrated circuit) on n-doped InP substrate. By optimization of the transistor´s base doping and the transistor geometry, an improvement of the frequency behavior has been achieved. The DC characteristic should be sufficient for application in an integrated circuit. together with the results of the 1.5- mu m SIBH laser on semi-insulating InP this appears to be a good basis for the realization of a transmitter OEIC consisting of a laser and a differential amplifier electronic circuit including resistors and capacitors.<>
