Fabrication tolerance impact on BIC metasurface resonances
2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2021Photonic bound states in the continuum (BICs) have recently emerged as an exciting toolkit for all-dielectric metasurfaces with sharp resonances and strong near-field enhancements. Specifically, metasurface unit cells with broken in-plane symmetry have unlocked precise control over the linewidth and therefore the quality factor (Q factor) of BIC-based ...

Fabrication of Nonperiodic Metasurfaces by Microlens Projection Lithography
Nano Letters, 2016This paper describes a strategy that uses template-directed self-assembly of micrometer-scale microspheres to fabricate arrays of microlenses for projection photolithography of periodic, quasiperiodic, and aperiodic infrared metasurfaces. This method of "template-encoded microlens projection lithography" (TEMPL) enables rapid prototyping of planar ...

Fabrication and Characterization of Large Area Plasmonic Metasurface Lenses.
Proposed for presentation at the 2022 Frontiers in Optics and Laser Science held October 17-20, 2022 in Rochester, NY US, 2022Metasurface lenses are fabricated using membrane projection lithography following a CMOS-compatible process flow. The lenses are 10-mm in diameter and employ 3-dimensional unit cells designed to function in the mid-infrared spectral range.

Aluminum nanoparticle deposition for scalable plasmonic metasurface fabrication
Plasmonics: Design, Materials, Fabrication, Characterization, and Applications XIX, 2021Large-area plasmonic metasurfaces have attracted interest as potential tools for a wide range of applications, from colorchanging glass to improved efficiency of solar cells. These potential applications necessitate the capability to fabricate such surfaces at scale. One potential approach to resolve this issue is to use nanoimprint lithography to mold

3D fabrication for optical metamaterials and metasurfaces
2016 Progress in Electromagnetic Research Symposium (PIERS), 2016Metamaterials enable the engineering of refractive index into the intriguing negative regime. Such negative index metamaterials (NIMs) can give rise to unique optical properties like negative refraction and backward waves. Similarly, zero index metamaterials (ZIMs) are widely studied recently for they open a new route to realize uniform phase ...
