Abstract

In this paper, we design an elliptical core silicon nanowire embedded spiral photonic crystal fiber (SN-SPCF) using fully vectorial finite element method. Further, we analyze the various optical properties, namely, waveguide dispersion, birefringence and effective nonlinearity by varying the ellipticity for a wide range of wavelengths from 0.450 μm to 2.050 μm. The proposed structure exhibits a high birefringence of 0.74143 for a small ellipticity of 0.3 at a longer wavelength of 2.05 μm. Besides, we investigate the evolution of supercontinuum generation both in spectral and temporal domains as a function of ellipticity at 1.550 μm wavelength for an input pulse of width 100 fs and peak power of 50W in a fiber of 2mm length. The numerical results corroborate that the proposed SN-SPCF provides a wider bandwidth of supercontinuum (600 to 2600 nm) and the findings of this work may be useful in ultrahigh-resolution optical coherence tomography.
