Degenerate Four Wave Mixing in Photonic Crystal Fibers


In this study, Four Wave Mixing (FWM) characteristics in photonic crystal fibers are investigated. The effect of channel spacing, phase mismatching, and fiber length on FWM efficiency have been studied. The variation of idler frequency which obtained by this technique with pumping and signal wavelengths has been discussed. The effect of fiber dispersion has been taken into account; we obtain that the influence of FWM can be reduced by irregular channel spacing. We use three wavelengths in the calculations (580, 780, and 1040nm) which are the zero dispersion wavelengths, all the results reported in this work are simulated using MATLAB 7.
