Advanced Optical Materials, EarlyView.A theoretical model is developed to visualize three‐dimensional refractive index profiles in transmission holographic gratings. In this work, it is applied to photopolymerizable hydrogels, enabling detailed analysis of the internal structure of recorded holograms and their evolution under different degradation conditions.

When Cubic is Not Isotropic: Phonon–Exciton Decoupling in CuInSnS4 Single Crystals
Advanced Optical Materials, EarlyView.A cubic CuInSnS4 crystal does not fully play by cubic rules. While phonons follow the average iso‐tropic lattice symmetry, the disorder‐localized excitons break away, showing strong, and reproduci‐ble polarization‐dependent emission. This work shows how intrinsic cation disorder can turn a mac‐roscopically cubic material into a source of hidden ...
