Abstract
Measurements of the gain and noise figure properties of a silica-fibre Raman amplifier operating at a central wavelength of 1555 nm are reported. Saturation of the gain is observed to occur for input powers exceeding 2 dBm in an amplifier with 20 dB small signal gain. An increase in the optical noise figure with input power by up to 0.5 dB was measured. Output powers of up to 1.4 W and 75% internal pump to signal conversion efficiencies are demonstrated.
