2D KTiOPO 4 photonic crystals are fabricated using a silicon membrane of air holes as a template. Columns of KTiOPO 4 are grown by liquid‐phase epitaxy from a substrate into such air holes. The crystallographic orientation of the columns is the same as that of the substrate. The photonic‐crystal properties of the fabricated structures and their capability to generate second‐harmonic light are experimentally demonstrated.
