Abstract

Dynamic power excursion imposed on the amplified signal due to relaxation oscillations in the laser and static residual variations in signal gain arising from spectral-hole burning (SHB) were observed in high-resolution measurements of laser automatic gain control (AGC) of erbium-doped fiber amplifiers (EDFAs). These effects will limit the ability of laser AGC to protect against power transients in amplified wavelength-division multiplexed (WDM) optical networks.
