Proceedings Paper

Achromatic metasurface optics operating in the visible spectrum (Conference Presentation)
Author(s): Victor M. Acosta; Maxwell Aiello

Paper Abstract

Metasurface optics provide an ultra-thin alternative to conventional refractive lenses. A present challenge is in realizing metasurfaces that exhibit tunable optical properties and achromatic behavior across the visible spectrum. I will discuss the design, fabrication, and characterization of metasurface lenses ("metalenses") that use asymmetric TiO2 nanostructures to induce a polarization-dependent optical response. These metalenses were used to demonstrate varifocal color imaging with white light from a halogen source. I will also provide an update on our efforts to fabricate stacked metasurfaces with multiple interacting layers that may offer enhanced performance across the visible spectrum.
