In this work, we studied modulational instability (MI) in an asymmetrical dual-core optical fiber with different power ratio at under normal (β2 >0) and anomalous dispersion (β2 < 0) regime. We investigate the variation of modulational instability for symmetric and asymmetric power. The result shows the influence of power in the frequency at which the MI gain appears. When the nonlinear coefficient...
In this work, we have studied the different optical parameters of octagonal photonic crystal fiber under different liquid filled core like water, toluene and carbon disulfide (CS2). The optical properties like effective index, dispersion coefficient and nonlinear coefficient has been observed for a wavelength range of 800nm to 1600nm. Each characteristic is studied using finite element method (FEM)...
In the present investigation we have proposed a solid core photonic crystal fiber (PCF) with octagonal ring structured cladding. In order to compare, two cases has been obtained with different air filling ratio and filled with high refractive index material. Different optical parameters of the photonic crystal fiber like effective area, Nonlinear Coefficient, Confinement Loss and Dispersion has been...
