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.

We present a novel single-polarization single-mode photonic crystal fiber (SPSM-PCF) design with four lines of small elliptical air-holes in order to obtain wider bandwidth for SPSM operation. The characteristics of the proposed SPSM-PCF are studied by using a full-vector finite element method (FEM) with perfect matched layer (PML) boundary conditions. At the wavelength of 1.55 µm, the confinement loss of the x-polarized mode is lower than 0.5 dB/km, whereas the loss of the y-polarized mode is larger than 50 dB/km. Compared with the case of x-polarized mode, the y-polarized mode can be suppressed in the PCF. Then, the SPSM operation is obtained. The proposed PCF can perform SPSM operation with broadband of 600 nm for considering the confinement loss ratio and the loss difference.
