High-gain erbium-doped traveling-wave fiber amplifier

E. Desurvire, J.R. Simpson, P. C. Becker

Traveling-wave amplification of a lambda = 1.53 microm signal with +22-dB gain is achieved at 295 K in an Er(3+)-doped single-mode fiber using a lambda = 514.5 nm pump source. The optimum fiber length for maximum gain is determined experimentally. A limit in signal-to-noise ratio that is due to concurrent amplification of spontaneous emission is observed. By cooling the fiber to 77 K, the amplifier gain is increased to +29 dB as a result of depopulation of the lower laser level.

The effect of upconversion on erbium-doped fiber amplifiers (EDFA)

Zhou Meng

Erbium-doped fiber amplifier(EDFA)efficiency strongly depends on erbium concentration.Highly doped erbium devices show degraded performance when compared with low concentration ones.The mechanism of upconversion is studied and the effect of it on the performance of an EDFA is analyzed numerically,by means of a set of rate equations model.Approximate analytical solutions,for the rate equations,which include the effect of the upconversion,are presented,when the amplified spontaneous emission can be neglected,compared to the pump and signal powers.Results show that the pump and signal powers all bear degradation due to upconversion.,and the effect can't be neglected when the Er3+ concentration is larger than 2.95×1025 m-3.

Analysis of the effect of upconversion on signal amplification in erbium-doped fiber amplifiers (EDFAs)

Inna Nusinsky, Amos A. Hardy

The effect of homogeneous upconversion on the performance of an erbium-doped fiber amplifier (EDFA) is analyzed numerically, by means of a set of rate equations model. In particular, the influence of pump power, signal power, and Er/sup 3+/ concentration on the degradation, due to upconversion, is examined. Forward pumping is considered and amplified spontaneous emission, as well as scattering loss are taken into account. In addition, approximate analytical solutions, for the rate equations, which include the effect of the cooperative upconversion, are presented. It is shown that under the considered conditions, these analytical solutions provide a good approximation to the exact numerical solution and thus may be used for the design of such amplifiers.
