| Abstract: | Spectral Raman amplification characteristics have been measured directly for a tunable pumping source, taking the relative polarization states of pump and signal waves into consideration. Raman amplification has been observed, even with an orthogonal polarization pump, in a long span single mode fiber. Raman amplification causes significant crosstalk in wave-length-multiplexed systems. |
