摘要

We present a complete analysis on improving the gain flatness of ultrabroadband tellurite fiber Raman amplifiers (TFRAs) by optimizing the parameters of multiwavelength pumps. Compared to conventional TFRAs, our amplifier has low gain ripple despite the ultrawide amplification bandwidth: well below 3.78% (5.66%, 11.98%) with respect to the average net gain 10 dB over a 120-nm (140-, 160-nm) bandwidth. In addition, we investigate the fractional gain contribution from each pump wavelength for the optimal 140-nm TFRA, and observe that the configuration is effective in equalizing the peculiar dual-peak gain spectra produced by multiple pumps. Finally, we calculate the noise figure for the 140-nm TFRA with a vibration less than 3 dB.
