Hybrid Resonant Metasurfaces with Configurable Structural Colors [link]Paper  doi  abstract   bibtex   
Abstract Metasurfaces are sub-wavelength nanostructures with the potential to overcome the limitations of traditional optics. Existing dielectric metasurfaces, however, are often limited to geometric primitives, which hamper their application in emergent hybrid metasurfaces. Here, a simple fabrication scheme for non-primitive metasurfaces that addresses this limitation is introduced. Due to their broken out-of-plane symmetry, these nanostructures provide a new dimension in the design space. Taking inspiration from bio-photonic systems in nature, using these elements complex hybrid metasurfaces are designed that encompass an ordered and a disordered phase. The capabilities of this hybrid optical systems are illustrated by generating configurable structural colors with extra ordinary resolution. Furthermore, the local control of light over a broad bandwidth is demonstrated and a maximum coupling efficiency of more than 97% is achieved.
