Abstract

A method for the fabrication of engineered planar defects inside opals (see Figure) is presented. These defects act as photonic microcavities, introducing a localized state in the gap. The scalability of the defect allows for the tuning of the spectral position of the defect by changing the size of the defect relative to the periodicity of the lattice.
