The aim of this paper is to study the dispersion of PBG-08 soft glass photonic crystal fiber (PCF). We investigate the possibility of generating broad band optical supercontinuum, by means of infiltrating the air-holes adjacent to the core of a hexagonal lattice PCF, by optical fluids of 5 refractive indices. The advantage of using PBG-08 instead of silica is its larger both transparency window (0.4 to 5 µm) and refractive index (n_F=1.9) let us infiltrate holes with fluids range from 1.3 to 1.8. The effective refractive index, dispersion, effective area and nonlinear profiles of fundamental mode for PCF infiltrated with various fluids are studied. Simulations reveal, in response to launching 100 fs input pulses of 1kW peak powers, with near zero dispersion wavelength centered about λ₀ = 1550 nm, into 10-cm long PBG-08 PCF infiltrated by Toluene with (n_F=1.5), a flat and broad supercontinuum can be achieved.
