Effect of anti-crossings with cladding resonances on ultrafast nonlinear dynamics in gas-filled photonic crystal fibers
Fig. 1. Effective refractive index of the fundamental core mode of (e) an ideal kagomé-PCF and (f) an SR-PCF, calculated using FEM (blue dots), and with the capillary model given by Eq. (
Fig. 2. (a) FWM dephasing for the kagomé-PCF, filled with 35 bar Ne. The slanted black line indicates degeneracy (signal and idler frequencies equal to the pump frequency). (b) Dephasing to DWs calculated under the same conditions, for an ideal anti-crossing-free fiber (dashed orange) and the real fiber filled with Ne at 35 bar (green).
Fig. 3. (a) Measured and (b) simulated spectrum at the kagomé-PCF output. (c) Maximum peak intensity along the fiber normalized to the input intensity (red squares) and conversion efficiency to the UV DW (blue dots) as a function of the wavelength of the
