Abstract
Frequency conversion through spontaneous degenerate four wave mixing (FWM) is investigated in large mode area hybrid photonic crystal fibers. Different FWM processes are observed, phasematching between fiber modes of orthogonal polarization, intermodal phasematching across bandgaps, and intramodal phasematching within the same transmission band as the one containing the pump laser. Furthermore first and second order Ra- man scattering is observed. The interplay between the different FWM processes and Raman scattering are investigated.
