Three Dimensional Optical Metasurfaces using Two-Photon Lithography
F. Balli, M. Sultan, S. Lami, D. Kumar, A. Thuringer, and J. Todd Hastings (University of Kentucky)
We review recent developments in 2.5 and 3D optical metasurfaces fabricated using two-photon lithography. Optical system of interest include achromatic metalenses, varifocal metalens, and focusing filters. We also present novel results in wide-color gamut imaging using arrays of focusing metafilters.
