Improved performance of volume holographic sol‐gel materials —refractive index modulations in the 10 –2 range, diffraction efficiencies near 100 %, and low levels of noise scattering—are reported that arise from the incorporation of Zr‐based high refractive index species capable of diffusing from dark to bright fringes of the interference pattern (see figure).
