High quality factor polariton resonators using van der Waals materials
Michele Tamagnone, Kundan Chaudhary, Christina M. Spaegele +6
We present high quality factor optical nanoresonators operating in the mid-IR to far-IR based on phonon polaritons in van der Waals materials. The nanoresonators are disks patterne…
A broadband achromatic polarization-insensitive metalens consisting of anisotropic nanostructures
Wei Ting Chen, Alexander Y. Zhu, Jared Sisler +2
Metasurfaces have attracted widespread attention due to an increasing demand of compact and wearable optical devices. For many applications, polarization-insensitive metasurfaces a…
Anisotropic Surface Plasmon Polariton Generation Using Bimodal V-Antenna Based Metastructures
Daniel Wintz, Antonio Ambrosio, Alexander Y. Zhu +2
V-shaped nanoantennas are among the popular choices for the unit element of a metasurface, a nanostructured surface used for its ability to mold and control the wavefront of light.…
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…
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…
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…
