Application of H∞ Control on Pilot Tones in Erbium-Doped Fiber Amplifiers

Abstract

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.
