A novel solid-core photonic bandgap (PBG) fiber with a square lattice is proposed. It is proved that light can propagate with the PBG effect in a defect core that is created by downdoping the central silica of the lattice. Compared with those of solid-core honeycomb PBG fibers, both the PBG widths and the bandwidthsof defect modes are increased in square PBG fibers. Simulations show that dispersion of this square solid-core PBG fiber is dominated by material dispersion and influenced by the PBG edges at the bandwidth boundaries.
