In this paper, wavelength conversion based on optofluidic infiltration of photonic crystal fibers (PCFs) is investigated to achieve the suitable wavelength over wide tunable range. For this purpose, two designs of PCFs (the so-called PCF1 and PCF2) with appropriate dispersion properties are simulated, and wavelength conversion via four-wave mixing process for pump wavelengths in both normal and anomalous dispersion regimes is studied. By changing the refractive index [Formula: see text] of the optical fluid infiltrated into the PCF air-holes and then varying the fiber dispersion properties, the converted wavelength region can be tuned. The results show that for the pump wavelength in the normal dispersion regime, the PCF1 infiltrated with [Formula: see text] and PCF2 infiltrated with [Formula: see text] exhibit the maximum wavelength shift. Moreover, the wavelength shift is much higher than that obtained in the anomalous dispersion regime and it can be further increased by increasing the input pump power.

Higher Order Effects

We consider the higher order nonlinear Schrödinger (HNLS) equation, which governs the nonlinear wave propagation in optical fibers with higher order effects. Lax pair associated with the integrable HNLS equation for the pulse propagation in normal dispersion regime of the fiber media is constructed with the help of Ablowitz–Kaup–Newell–Segur method. Using Hirota bilinear method, dark soliton solution is explicitly derived. Similar study is also carried out for simultaneous propagation of N nonlinear pulses in the normal dispersion regime of the fiber system with higher order effects.
