Application of H! Control for Pilot Tones in Erbium-doped Fiber Amplifiers

In this paper we propose the application of H! control within optical networks. Specifically, we aim to suppress the cross-gain modulation effects within Erbium-doped fiber amplifiers owed to pilot tone disturbances used for optical monitoring. Based on the characteristics of these pilot tone disturbances, we design an H! controller to improve transient performance of optical channels within the network. Within this paper the control system design is described and simulation results are presented.
