Abstract
Woodpile photonic crystals are derived from a diamond lattice by modification of the unit cell according to layer-by-layer fabrication convenience. The fabrication may be simplified even more if the overlap between adjacent layers is allowed. Here we describe the fabrication of such an overlapped-woodpile crystal. Its optical characteristics are studied numerically, and the existence of a photonic bandgap for specific parameters is demonstrated.
