The operation of a continuous-wave (CW) single-wavelength pumped fibre optic parametric amplifier operating in the S+-band with simultaneous wavelength conversion to the C-band is demonstrated. Peak gain of 25 dB at 1518 nm and gains higher than 10 dB from 1510 to 1530 nm were obtained using 480 m of a fibre with a nonlinear coefficient γ=12.2 W−1 km−1, requiring a pump power of 660 mW. Simultaneously, idler wavelengths were generated in the C-band with a peak conversion efficiency of 25 dB at 1552 nm.
