Monolithic integration of laser diodes, photomonitors, and laser driving and monitoring circuits on a semi-insulating GaAs

A monolithic optoelectronic-integrated circuit (OEIC) incorporating laser diodes, photomonitors, and laser driving and monitoring circuits has been fabricated on a semi-insulating GaAs substrate. The structure and circuit design considerations, the fabrication processes, and the static and dynamic characteristics of the device are described. The device has been successfully operated up to 2 Gbit/s.
