Journal ArticleDOI
Optical spin-symmetry breaking for high-efficiency directional helicity-multiplexed metaholograms
Muhammad Ashar Naveed,Muhammad Afnan Ansari,Inki Kim,Trevon Badloe,Joohoon Kim,Dong Kyo Oh,Kashif Riaz,Tauseef Tauqeer,Usman Younis,Murtaza Saleem,Muhammad Sabieh Anwar,Muhammad Zubair,Muhammad Qasim Mehmood,Junsuk Rho +13 more
TL;DR: This paper demonstrates an asymmetric SOI-dependent transmission-type metasurface in the visible domain using hydrogenated amorphous silicon (a-Si:H) nanoresonators and demonstrates the concept of asymmetric wavefront generation in two antiparallel directions.
Journal ArticleDOI
Nanoimprint lithography for high-throughput fabrication of metasurfaces
TL;DR: In this article, a review of various nano-imprint lithography (NIL) technologies for the manufacturing of active metasurfaces is presented, where the authors briefly describe conventional NIL and then present various NIL methods for the scalable fabrication of active surfaces.
Journal ArticleDOI
Broad-Band Polarization-Insensitive Metasurface Holography with a Single-Phase Map.
Isma Noreen Javed,Joo-Suc Kim,Muhammad Naveed,Dong Kyo Oh,Dongmin Jeon,In-Cheol Kim,Muhammad Zubair,Y. Massoud,Muhammad Qasim Mehmood,Junsuk Rho +9 more
TL;DR: In this paper , a geometric phase-enabled novel design strategy is proposed to break the conventional trade-off between polarization-insensitivity and bandwidth, which ensures the realization of broad-band polarization sensitivity through a simplified design procedure.
Journal ArticleDOI
Single-Step Fabricable Flexible Metadisplays for Sensitive Chemical/Biomedical Packaging Security and Beyond.
Muhammad Naveed,Joo-Suc Kim,Muhammad Afnan Ansari,In-Cheol Kim,Y. Massoud,Jaekyung Kim,Dong Kyo Oh,Trevon Badloe,Jihae Lee,Ye-Hoon Kim,Dongmin Jeon,Jonghyun Choi,Muhammad Zubair,Muhammad Qasim Mehmood,Junsuk Rho +14 more
TL;DR: In this article , a broad-band polarization-insensitive flexible metasurface for the security of sensitive packages in the transport industry is proposed, which employs both the propagation and the geometric phase of novel TiO2 resin-based anisotropic nanoresonators.
Journal ArticleDOI
Top-down nanofabrication approaches toward single-digit-nanometer scale structures
TL;DR: In this paper, the authors discuss the recent advances in top-down nanofabrication methods towards single-digit-nanometer-sized structures and discuss state-of-the-art applications for sub-10 nm nanophotonics such as optical trapping or sensing devices, imaging devices, and electronic devices.
