Paper Abstract

Noise can limit the power in a fiber amplifier by competing with the signal for gain. Disributed filtering offers a way of overcoming current high-power limitations by selectively removing noise before it is amplified. Resonant mode suppression is a flexible strategy for wavelength filtering as well as suppression of unwanted transverse modes. An Yb-doped gain fiber with distributed filtering of stimulated Raman scattering (SRS) was demonstrated in a cladding-pumped amplifier. Substantial suppression of SRS was demonstrated in this fiber, with a core and resonant Ge-doped ring made using standard solid-fiber fabrication. Simulations explore generalizations to large-mode-area and filters with multiple band-stop features.
