Characterisation of semiconductor optical amplifiers for all-optical regeneration

Abstract

OralInternational audienceWe report on the characterisations of different semiconductor optical amplifiers (SOA) which are designed and fabricated for All-Optical Regeneration. Dynamic measurements in pump-probe configuration show short time response of around 50 ps. Chirp measurements by FROG technique are also reported. The characterisations demonstrate the potential of these components to be associated with interferometer and optical filtering in order to achieve regeneration functions at bit rates of 40 Gbit/s and above
