Blue shift effect on the reflectance in two-dimensional Si-ZnO photonic structure with patterned coupled optical micro-cavities

Abstract

This research has revealed the possibility to induce a shift towards short wavelengths on the optical reflectance properties of a two-dimensional photonic crystal which include an embedded array of optical micro-cavities. This ability was attributed to the resonant effect produced by the micro-cavities array embedded in the regular photonic crystal and by the variation on the structural parameters that defined the photonic crystal under research. These results can be useful in future applications of solar cell systems and telecommunications, among others, which can be of great help to increase technological developments.
