High‐refractive‐index, 3D photonic crystals (see Figure) are produced by silicon double inversion of a polymer woodpile template fabricated by multiphoton direct laser writing. The method incorporates silica chemical vapor deposition fine‐tuning of the filling fraction of an intermediate silica inverted woodpile, and thus the ability to tailor the width of the complete photonic band gap of the silicon woodpile.
