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.enclocksoptical bistabilityoptical fibre networksoptical switchessemiconductor switchestiming circuitswaveguide lasers2.5-Gbit/s all-optical clocked decision circuitretiming circuitbistable semiconductor lasersoptical signal processingflexible transparent optical communication networksall-optical signal regenerationtwo-section fabry- perot semiconductor laserridge-waveguide typeabsorber sectionsgood switching characteristics2.5 Gbit/s621conference paper
