In this study, we consider band structures of two classes of photonic crystals with two geometric parameters. The first class has a square lattice and is studied for dielectric contrast, centered at $\varepsilon/\varepsilon_{0}=11.4$ (GaAs-air). The second class has a hexagonal lattice and is studied for dielectric contrast, centered at $\varepsilon/\varepsilon_{0}=13$ (silicon-air). These examples have the following feature: the optimal (and largest) full band gap is obtained when both band gaps for $E$ and $H$ polarizations have the same (simultaneous) band edges. In addition, photonic crystals with two geometric parameters typically have much larger optimal band gaps than their counterparts with one geometric parameter.
