Phase and dispersion engineering of metalenses: broadband achromatic focusing and imaging in the visible
Wei Ting Chen, Alexander Y. Zhu, Vyshakh Sanjeev +4
Metasurfaces have the potential to miniaturize and improve the performance of any optical element, with applications spanning telecommunications, computing and wearable optics. How…
Achromatic Metalens in the Visible and Metalens with Reverse Chromatic Dispersion
M. Khorasaninejad, Z. Shi, A. Y. Zhu +4
In this letter, we experimentally report an achromatic metalens (AML) operating over a continuous bandwidth in the visible. This is accomplished via dispersion engineering of diele…
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…
Dispersion-compensated meta-holograms based on detour phase
Mohammadreza Khorasaninejad, Antonio Ambrosio, Pritpal Kanhaiya +1
Subwavelength structured surfaces, known as metasurfaces, hold promise for future compact and optically thin devices with versatile functionalities. Here, by revisiting the concept…
