Abstract

One of many fiber non-linear effects is a four-wave mixing (FWM) phenomenon that is resonant when phase matching condition is satisfied. It only occurs for particular combinations of fiber dispersion and signal frequencies. In particular, phase matching is achieved for signals with very similar frequencies propagating near the zero dispersion wavelength of the fiber. This paper proposes optical wavelength conversion based on FWM assisted by Raman amplification. The conversion bandwidth extends to 125nm, the widest yet reported for wavelength conversion using highly non-linear fiber (HNLF) irrespective to the conversion efficiency value. The 1R property defined when conversion efficiency (CE) is positive was found to cover an area of 19.5nm
