Anisotropic shrinkage of holographic 3D photonic crystals is quantified and precompensated by exposure to an appropriately spatially stretched interference pattern. The resulting simple-cubic overall symmetry is validated by means of focused-ion-beam cuts (see figure), optical transmission measurements, and comparison with theory.
