Simultaneous S super( +)-band amplification and S super( +)-C-band wavelength conversion in CW pumped fibre optic parametric amplifier

The operation of a continuous-wave (CW) single-wavelength pumped fibre optic parametric amplifier operating in the S super( +)-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, us...

Zusammenfassung:The operation of a continuous-wave (CW) single-wavelength pumped fibre optic parametric amplifier operating in the S super( +)-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 gamma =12.2 W super( -1) km super( -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.
