Designing large, high-efficiency, high-numerical-aperture, transmissive meta-lenses for visible light
Byrnes, Steven Feinman; Lenef, Alan; Aieta, Francesco; Capasso, Federico (The Optical Society, 2016)A metasurface lens (meta-lens) bends light using nanostructures on a flat surface. Macroscopic meta-lenses (mm- to cm-scale diameter) have been quite difficult to simulate and optimize, due to the large area, the lack of ... -
Enhancement of Absorption and Color Contrast in Ultra-Thin Highly Absorbing Optical Coatings
Kats, Mikhail A.; Blanchard, Romain; Kolle, Mathias; Genevet, Patrice; Aizenberg, Joanna; Capasso, Federico; Byrnes, Steven (AIP Publishing, 2013-09-02)Recently a new class of optical interference coatings was introduced which comprises ultra-thin, highly absorbing dielectric layers on metal substrates. We show that these lossy coatings can be augmented by an additional ...
