Ordinary step-type fiber usually has only one obvious Brillouin scattering gain peak with a low gain coefficient, resulting in a poor sensing performance. As a promising material for nonlinear photonics, lithium niobate can significantly improve the

We have demonstrated an erbium doped fiber amplifier (EDFA) gain equalizer for flattening the amplified spontaneous emission gain spectrum using a Sagnac loop incorporated with a single-section unpumped erbium-doped fiber. The gain spectra output fro
