Abstract :
A double-pumped parametric amplifier where stimulated Brillouin scattering is suppressed by applying a strain distribution along the fibre plus a low-frequency (140 MHz) pump phase modulation is presented. The good performance of the amplifier, confirmed by eye measurements at 10 Gbit/s, indicates that the method of straining fibres to eliminate completely SBS may be effectively implemented, improving these devices.
