Guided Modes of Anisotropic van der Waals Materials Investigated by Near-Field Scanning Optical Microscopy
Daniel Wintz, Kundan Chaudhary, Ke Wang +11
Guided modes in anisotropic two-dimensional van der Waals materials are experimentally investigated and their refractive indices in visible wavelengths are extracted. Our method in…
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…
