Abstract :
A proposed novel technique for highly-efficient optical fibre wavelength converters based on four-wave mixing is demonstrated. The spread spectrum of pump light has been shown to be effective in suppressing stimulated Brillouin scattering, yet results in the spread of the converted spectrum. To avoid this, modulating the pump and signal lights synchronously is proposed. Cancellation of the spectral spread and the highly-efficient wavelength conversion is demonstrated experimentally
