Abstract :
Wavelength-dependent measurements of the nonlinear figure of merit (FOM) in a highly nonlinear As2Se3 chalcogenide fibre, from 1415 to 1554 nm, are presented. It is found that the FOM decreases monotonically towards shorter wavelengths, as the material half-bandgap is approached. The FOM > 1 for wavelengths above 1450 nm suggests applications for nonlinear optics in the C-band.
