Paper Abstract

An analytic computer-oriented model for the Er / Yb co-doped silicate fiber amplifier is presented. The model is based on iterative solving the rate and propagation equations in their recursive forms at uniform discrete points along the fiber. It is capable of handling double-clad multimode-pumped fiber configurations, as well as conventional single-mode-pumped ones (with the signal featuring single-mode propagation in both cases). Arbitrary number of signals and pumps including wavelength-multiplexed ones from any direction can be treated. Amplification-deteriorating physical effects characteristic of the Er / Yb co-doped system, such as Yb amplified spontaneous emission, Er direct pumping, Er ions up-conversion and pairs formation, pump excited-state absorption and Er - Yb back-transfer, have been accounted for, in addition to the direct Yb - Er energy transfer. The relative importance of these effects in the amplification process has been modeled and discussed on the basis of experimentally determined fiber physical parameters.
