A Reflective Metasurface for High-Efficiency Terahertz Cross-Polarization Conversion
Muhammad Fayyaz Kashif, Shobit Agarwal, Antonio Iodice +5
We demonstrate a reflective terahertz (THz) polarization conversion metasurface based on a double-ring aluminum resonator on a quartz substrate. Full-wave simulations are used to o…
Deterministic Bottom-Up Fabrication of Plasmonic Nanostructures on Optical Nanofibers via Blurred Electron Beam Deposition
Antonio Balena, Marianna D Amato, Muhammad Fayyaz Kashif +4
This study introduces a novel method for the deterministic fabrication of metallic nanostructures with controlled geometry and composition on suspended, single mode tapered optical…
Direct Nucleation of Hierarchical Nanostructures on Plasmonic Fiber Optics Enables Enhanced SERS Performance
Di Zheng, Riccardo Scarfiello, Muhammad Fayyaz Kashif +8
We present an innovative fabrication method to achieve bottom-up in situ surface-overstructured Au nanoislands (NIs) with tunable grades of surface coverage, elongation, and branch…
Tunable Nanoislands Decorated Tapered Optical Fibers Reveal Concurrent Contributions in Through-Fiber SERS Detection
Di Zheng, Muhammad Fayyaz Kashif, Linda Piscopo +4
Creating plasmonic nanoparticles on a tapered optical fiber tip enables a remote SERS sensing probe, ideal for challenging sampling scenarios like biological tissue, specific cells…
