Abstract：

We explore the fabrication and characterization of GaN semiconductor based metasurfaces. Several nanofabrication approaches are discussed including free standing metasurface membranes, direct etching and sublimation of GaN metastructures to deflect and focus light at visible wavelength. We propose a new approach to compensate the effect of chromatic dispersion in refractive material with metasurfaces. We will also introduce the concept of conformal boundary optics to design arbitrary photonic response of conformal metasurfaces.
