Abstract
Transient gain dynamics in doped-fiber amplifiers have been studied intensively in connection with sudden channel addition or removal caused by either unintentional failures, or by deliberate network reconfigurations.1,2 The main concern here is in the duration of the power transients, which may induce temporary performance degradation, and the amount of power surges, which may damage the optical components and cause system disruption. Such transients are connected to the population dynamics of the dopant ions, and can be much faster than the ions relaxation time, depending on the signals saturating power.2–4
