| Abstract: | We propose a simple method for all-fiber wavelength conversion of ultra-fast signal by means of stimulated Raman scattering. The idea is based on the transference of energy from the signal as pump to a desired signal as first Stokes by stimulated Raman scattering. To minimize the walk-off between two wavelengths, we chose the input signal and the desired output signal wavelengths, equally spaced on opposite sides of the zero dispersion wavelength of the fiber. Based on this assumption, we numerically analyzed the all-fiber wavelength converter for ultra-fast signal with high output power and significantly enhanced output extinction ratio. |
