Abstract

We propose the use of four-wave mixing (FWM) in optical fibres to extend the range of available wavelengths from gas-cell based standards. Optical frequency references based on lasers locked to transitions in Acetylene and HCN are used in 1.5 µm spectral region to provide absolute reference points. By appropriate selection of the transitions it is possible to synthesise lines that closely match the ITU frequency grid. The effects of dispersion of the optical fibres on the efficiency of the FWM have been shown experimentally.
