Such fibres ,can be used for applications including optical data regeneration, wavelength conversion, optical demultiplexing, and Raman amplification. The usual measure of fibre nonlinearity is the effective nonlinearity γ. Even though silica is not a particularly nonlinear material (n are possible in pure silica microstructured fibres.enConference paper00200524212008032015265753655Ebendorff-Heidepriem, H.
