The single‐step fabrication of 3D electro‐optical photonic crystals is described. Holographic polymerization of a monomer–liquid crystal mixture is employed, whereby liquid crystal separates as nanoscale droplets at crystal lattice or interstitial points within a crosslinked polymer matrix. The Figure shows the laser intensity pattern in the xy ‐plane for recording an orthorhombic photonic crystal.
