We study nonlinear spectral broadening and supercontinuum generation mechanisms in two-dimensional solid-core photonic bandgap fibers. Using rigorous frequency-domain numerical simulations, we determine how the spectral characteristics are influenced by the strong frequency dependence of the effective area, dispersion, and confinement losses. We also investigate soliton stabilization and the conditions under which efficient nonlinear spectral energy transfer is possible across high attenuation between adjacent bandgaps. Our results provide insight into recent experiments.
