We experimentally demonstrate how a concatenation of standard and microstructure fiber segments permits adjusting the Four-Wave-Mixing sideband position over a large spectral range by varying the chirp of an input pulsed pump at a fixed wavelength. The blue- and red-shifted sidebands can stand aside over ~ 200 nm and ~ 450 nm from the pump, respectively, which agrees well with the numerical simulations. We validate our approach by showing the feasibility of CARS imaging.
