Abstract:Hybrid two-dimensional photonic crystal structure described by a square lattice of circular air columns with embedded quasi-circular micro-cavities in a square array was fabricated on Si-ZnO substrate using the focused ion beam (FIB) technique. The optical characterization of this photonic device revealed its ability to selectively enhance the reflectance on specific wave lengths in the border of visible-near-infrared range (VIS-NIR). The behavior of the photonic hetero-structure built and studied in this work… Show more
