Design and fabrication of dielectric metasurfaces for optical wavefront manipulation

Optical metasurfaces have emerged as an attractive platform for manipulating the wavefront of light. Due to their compact form factor and compatibility with semiconductor fabrication, metasurfaces offer a promising optical platform for compact integration with electronics. In this work, we demonstrate the metasurface engineering workflow through design and fabrication. We outline the conventional forward design and inverse design strategies for metasurfaces tailored to shape spatial optical wavefronts, and further demonstrate their experimental realization using standard nanofabrication techniques.
