Abstract

In this paper, the amplification mechanism of ultra-wide-band telluride-based fiber Raman amplifier (T-FRA) is described, and the Raman gain coefficient spectra of telluride-based fiber are studied thoroughly by compare the stimulated Raman scattering (SRS) characteristics of the telluride-based fiber with silica-based fibers. First, the cooperation of phonons and photons in telluride-based fibers is analyzed. Then the reason why Raman scattering of the telluride-based fibers can lead to a large gain coefficient and Stokes shift is discussed. The physical basis is analyzed in this paper and the energy of molecular vibration is taken into account. A multi-pumping scheme is provided at the end of the paper to apply gain-flattened T-FRA to WDM system.
