Abstract
Abstract An AlGaAs based standard photonic crystal fiber structure is reported for low dispersive nonlinear optics applications. By employing a finite element solver with perfectly matched layer boundary condition, the key propagation characteristics are investigated over a broad wavelength span (1–5 μm) by taking the different air filling fraction values. The proposed work provides an effective fundamental mode area of 7.30 μm2 with nonlinearity in the order of 8.325 W−1m−1 at a low absorption wavelength of 1.55 μm and zero-dispersion wavelength close to 3 μm.
