Abstract

A fiber amplifier based on Yb-doped Symmetry-Free Photonic Crystal Fiber has been studied through the use of a numerical tool. The amplification properties and the modal content of the amplifier have been investigated in conditions of severe heat load, in order to understand the effectiveness of amplification dynamics. The numerical tool, used for this study, is based on a FEM modal solver combined with a model which allows to evaluate amplification and thermal effects. Results depict a scenario where it is possible to obtain a good mode discrimination and a robust amplification under critical thermal condition.
