We analyze the modulational instability process induced by periodic variations of the parameters of a PCF along the propagation direction, induced by an analogue of the parametric resonance in mechanics.
We present here a measurement of the temperature dependence of the zero dispersion wavelength in an air/silica photonic crystal fiber. This is done through a simple method based on a fourth-order four-wave mixing process by pumping the fiber in a low normal dispersion regime. The zero dispersion wavelength is found to increase by about 10 nm from room temperature to 250 . This result...
From a standard point of view Modulational Instability (MI) process leads to the formation of two symmetric spectral side lobes [1]. In optical fibers, it has been shown that working in low anomalous dispersion regions, the slope of the dispersion leads to a symmetry breaking of the spectrum and to the generation of dispersive waves (DW) [2]. In this work, we demonstrate both numerically and experimentally...
