Ultrafast all-optical switching enabled by epsilon-near-zero modes in metal-insulator nanocavities
Joel Kuttruff, Denis Garoli, Jonas Allerbeck +5
Ultrafast control of light-matter interactions constitutes a crucial feature in view of new technological frontiers of information processing. However, conventional optical element…
Nanoparticles manipulation in 3D nanotips excited with plasmonic vortex
Xue Jin Zhang, Yuefeng Shen, Kai Liu +4
Recent advances in nanotechnologies have prompted the need for tools to accurately and non invasively manipulate individual nanoobjects. Among the possible strategies, optical forc…
Single-molecule DNA Bases Discrimination in Oligonucleotides by Controllable Trapping in Plasmonic Nanoholes
Jian-An Huang, Mansoureh Z. Mousavi, Yingqi Zhao +6
Surface-enhanced Raman spectroscopy (SERS) sensing of DNA sequences by plasmonic nanopores could pave a way to new generation single-molecule sequencing platforms. The SERS discrim…
Site-selective functionalization of plasmonic nanopores for enhanced fluorescence and Förster Resonance Energy Transfer
Xavier Zambrana-Puyalto, Nicolò Maccaferri, Paolo Ponzellini +3
In this work, we use a site-selective functionalization strategy to decorate plasmonic nanopores with one or more fluorescent dyes. Using an easy and robust fabrication method, we…
MIM Structure for optical vortex beam generator at nanoscale level
Denis Garoli, Pierfrancesco Zilio, Yuri Gorodetski +2
Optical beams carrying orbital angular momentum (OAM) can find tremendous applications in several fields. In order to apply these particular beams in photonic integrated devices in…
Magnetic Control of Transmission and Helicity of Nano-Structured Optical Beams in Magnetoplasmonic Vortex Lenses
Nicolò Maccaferri, Yuri Gorodetski, Andrea Toma +3
We theoretically investigate the generation of far-field propagating optical beams with a desired orbital angular momentum by using an archetypical magnetoplasmonic tip surrounded…
