Abstract :
Transmission over 150 km of standard fibre at 5 Gbit/s, and over 75 km at 8 Gbit/s, is reported with a monolithically integrated DFB laser and Franz-Keldysh absorption modulator. The modulator facet reflectance is low. The device is stable over a range of operating parameters. The butt-joint, buried-heterostructure device is entirely grown by MOVPE.
