Abstract
A gain-flattened tellurite-based fiber Raman amplifiers (T-FRA) is proposed and numerically demonstrated. By solving the steady equation of a T-FRA, the characteristics including the gain and gain flatness of T-FRA is investigated. The results show that a T-FRA pumped by dual wavelengths can provide gain-flattened band with widths of 48 nm. Moreover, the average gain and gain flatness is 17.72 dB and 0.68 dB, respectively. The newly designed T-FRA is very promising in future optical fiber communication systems.
