Abstract
A novel idea to reduce the noise level in Raman fiber amplifiers is theoretically proposed with help of Ge-doped Raman fiber amplifier and second Stokes control pulses in temporal domain. By removing an inter-pulse noise power in signal pulses at the first Stokes' wavelength that is amplified a lot normally during an optical amplification, signal-to-noise ratio for signal pulses after amplification can be enhanced. The noise power removal is performed by transferring the noise power to the second Stokes' one using the stimulated Raman scattering. In addition, we discuss several kinds of second Stokes control pulses and the effect of double Rayleigh back-scattering.
