Abstract

Conventional erbium-doped fiber amplifier (EDFA) control schemes lack a systematic design approach and do not consider the characteristics of system input disturbances. We propose the application of H_infin control to suppress the cross-gain modulation effects of pilot tones, used for optical monitoring, and packet and burst-switched traffic, commonly found in optical burst switched networks. A detailed design of the H_infin controller is given, focusing on the characteristics of the input disturbances and desired performance measures. Simulation results under different types of disturbances are presented showing significant improvements in response time and reductions in power excursions
