Polarization Modulation Instability in Dispersion-Engineered Photonic Crystal Fibers

Investigation of Scalar Modulation Instability in the Presence of Raman Scattering in Photonic Crystal Fibers

In this paper, by including Raman scattering in the coupled-mode equations, the scalar modulation instability in photonic crystal fibers is investigated. The evolution of the pump, Stokes and anti-Stokes waves along the fiber as well as the conversion efficiency for two cases, with and without Raman effect, are studied. The effect of anti-Stokes seed and the pump depletion on the evolution of S...

Second-order polarization-mode dispersion in photonic crystal fibers

Polarization-mode dispersion of large mode-area photonic crystal fibers

We report on an experimental study of the polarization properties of large mode-area photonic crystal fibers (PCFs). We find that such fibers may exhibit very low birefringence and polarization-mode dispersion (PMD) indicating a highly symmetrical hole structure over a long length. Moreover, the influence of temperature on the polarization-mode dispersion is investigated. The results show that ...

Investigation of FWM in dispersion-engineered GaInP photonic crystal waveguides

We report on the investigation of four-wave mixing (FWM) in a long (1.3 mm) dispersion-engineered Gallium Indium Phosphide (GaInP) photonic crystal (PhC) waveguide. A comparison with a non-engineered design is made with respect to measured FWM efficiency maps. A striking different response is observed, in terms of dependence on the pump wavelength and the spectral detuning. The benefits and the...

Demonstration of ultra-flattened dispersion in photonic crystal fibers.

We demonstrate photonic crystal fibers with ultra-flattened, near zero dispersion. Two micro-structured fibers showing dispersion of 0 +/- 0.6 ps/nm.km from 1.24 microm-1.44 microm wavelength and 0 +/- 1.2 ps/nm.km over 1 microm-1.6 microm wavelength have been measured.
