We experimentally demonstrate the phase matching curve for the Four-Wave-Mixing effect of Bragg Scattering in two Highly-Nonlinear-Fibers with opposite sign 4th order dispersion coefficients. The experimental results are fitted to theoretical predictions with good agreement.
Optical parametric amplification is an important nonlinear process in photonic crystal fibres driven by the small effective area and the special dispersion characteristics of these fibres. Aside from its role in supercontinuum generation, parametric amplification can lead to efficient wavelength conversion, limited primarily by the uniformity of the diameter of currently available fibres. The related...
