We demonstrate a large area production of 3-D woodpile metallic photonic crystals using deep x-ray lithography and subsequent electroforming. These structures represent the 110 orientation of the 001 woodpile structures most commonly presented in the literature. This approach requires no alignment and is capable of generating a 3 unit cell thick photonic crystal in a simple three step process flow. Tilted woodpiles demonstrate band characteristics very similar to those observed from [001] woodpiles. Reflectivity tests show a band edge around 4 µm and good comparison well with numerical simulations.
