2.5-Gbit/s all-optical clocked decision and retiming circuit using bistable semiconductor lasers

Summary form only given. Optical signal processing is a key technology for the construction of flexible, transparent optical communication networks, and all-optical signal regeneration is an important task. Our experiments were performed with a two-section Fabry- Perot semiconductor laser of the ridge-waveguide type. The lengths of gain and absorber sections were optimized for good switching characteristics. Details of the device and its preparation are described.
