Abstract

A numerical model for the analysis and the designof S band erbium-doped fiber amplifiers has been developed. Themodel is able to accurately predict the amplifier performancesby taking into account the ASE suppression due to the bending,as well as leakage losses of the fiber used as active medium.The model has been validated by comparing numerical andexperimental data of bending loss, amplifier gain and noise figureof a S band optical amplifier based on a depressed-claddingerbium-doped fiber. A good agreement has been verified byvarying fiber bending radius, input signal power and wavelength.The model has been then applied to the optimization of theamplifier performances for WDM applications. The numericalresults show that 20 − 25 dB gain can be achieved over a25 − 30nm range centered in different part of the S band from1460nm to 1525nm, just by changing the bending radius andthe length of a depressed-cladding fiber.
