Abstract The B2O3-doped silicate photonic crystal fiber (PCF) containing small core and dielectric rods made of lead silicate SF57 has been most intensively investigated for different pump signals centered at 0.65 mm, communication band. This type of doping has been carried out to significantly diminish the upgraded refractive index of silica which enhances special capabilities that lead to an outstanding potential to PCF for the profoundly intense field in the optical Kerr effect. In this paper, the mode analysis has been done by solving a nonlinear wave equation for a Gaussian input beam using the finite difference method under analytical boundary conditions. Numerical results reveal that very minute doping of B2O3 is enough in giving prolonged confinement of beam with flattened dispersion due to ultra-low change in nonlinear behaviour.
