Fig. 7From: Lowering backward Raman and Brillouin scattering in waveguide Raman wavelength convertersExperimentally measured output energies versus the incident pump energy. The green disks correspond to the transmitted pump, the red stars correspond to the forward Raman and the brown triangles correspond to the reflected Brillouin. The lines correspond to the simulations (see text). Left figure is for a fiber length of L = 0.5 m and the right one is for L = 1.5 mBack to article page
