Ellipse Core Based Photonic Crystal Fiber with High Nonlinearity and Higher Numerical Aperture

A nobly designed photonic crystal fiber has been proposed with ellipse core for higher nonlinearity and higher numerical aperture in this study. This design can sense aqueous analysis over a wavelength range of (1.00 µm to 1.6 µm). The numerical solution has been done using Finite Element Method (FEM) employing a boundary condition. The proposed model provides a high nonlinearity of 1.10×10s W−1Km−1 along with the numerical aperture of 0.795 at operating wavelength of 1 µm & 1.55 µm respectively for fundamental single mode operation and the effective area have further discussed. The structure is pragmatic for sensing and laser applications. This model may also find comprehensive operation in spectroscopy and imaging.
