Stimulated Brillouin scattering threshold in double-clad fibers with various cladding shapes

Stimulated Brillouin scattering threshold in double-clad fibers with various cladding shapes
We present a detailed numerical investigation about the stimulated Brillouin scattering (SBS) threshold power of double-clad optical fibers having different inner-cladding shapes. Generally, fibers with broken symmetry inner-cladding are usually employed in fiber lasers and amplifier in order to enhance pump light absorption by the doped core [1]. The acoustic response of such geometries is not known because their numerical characterizations are complicated. Even more difficulties occur when the fiber possess an acoustic anti-waveguide core since in that case the Brillouin response is often ruled by very high-order modes.

Abstract

We present a detailed numerical investigation about the stimulated Brillouin scattering (SBS) threshold power of double-clad optical fibers having different inner-cladding shapes. Generally, fibers with broken symmetry inner-cladding are usually employed in fiber lasers and amplifier in order to enhance pump light absorption by the doped core [1]. The acoustic response of such geometries is not known because their numerical characterizations are complicated. Even more difficulties occur when the fiber possess an acoustic anti-waveguide core since in that case the Brillouin response is often ruled by very high-order modes.
