Antireflection by design in bilayer metasurfaces
Jaewon Oh, Davide Cassara, Alfonso Palmieri +5
Antireflection coatings are ubiquitous in optical systems, where they maximize transmission and suppress undesirable reflections by impedance-matching uniform interfaces. Extending…
Shape optimization for high efficiency metasurfaces: theory and implementation
P. Dainese, L. Marra, D. Cassara +7
Complex non-local behavior makes designing high efficiency and multifunctional metasurfaces a significant challenge. While using libraries of meta-atoms provide a simple and fast i…
Do bilayer metasurfaces behave as a stack of decoupled single-layer metasurfaces?
Alfonso Palmieri, Ahmed H. Dorrah, Jun Yang +3
Flat optics or metasurfaces have opened new frontiers in wavefront shaping and its applications. Polarization optics is one prominent area which has greatly benefited from the shap…
Metasurfaces for free-space coupling to multicore fibers
Jaewon Oh, Jun Yang, Louis Marra +4
Space-division multiplexing (SDM) with multicore fibers (MCFs) is envisioned to overcome the capacity crunch in optical fiber communications. Within these systems, the coupling opt…
Spin-to-orbital angular momentum conversion in dielectric metasurfaces
Robert Charles Devlin, Antonio Ambrosio, Daniel Wintz +6
Spin-to-orbital-angular-momentum conversion has attracted considerable interest as a tool to create exotic light beams, leading to the emergence of novel devices that implement thi…
Planar Lenses at Visible Wavelengths
Mohammadreza Khorasaninejad, Wei Ting Chen, Robert C. Devlin +3
Sub-wavelength resolution imaging requires high numerical aperture (NA) lenses, which are bulky and expensive. Metasurfaces allow the miniaturization of conventional refractive opt…
High efficiency dielectric metasurfaces at visible wavelengths
Robert C. Devlin, Mohammadreza Khorasaninejad, Wei-Ting Chen +2
Metasurfaces are planar optical elements that hold promise for overcoming the limitations of refractive and conventional diffractive optics1-3. Dielectric metasurfaces demonstrated…
