Gain-Assisted Optomechanical Position Locking of Metal/Dielectric Nanoshells in Optical Potentials
Paolo Polimeno, Francesco Patti, Melissa Infusino +6
We investigate gain-assisted optical forces on dye-enriched silver nanoshell in the quasi-static limit by means of a theoretical/numerical approach. We demonstrate the onset of non…
Faster calculations of optical trapping using neural networks trained by T-matrix data: an application to micro and nanoplastics
Shadi Rezaei, David Bronte Ciriza, Abdollah Hassanzadeh +5
We employ neural networks to improve and speed up optical force calculations for dielectric particles. The network is first trained on a limited set of data obtained through accura…
Optical Calibration of Holographic Acoustic Tweezers
Sonia Marrara, David Bronte Ciriza, Alessandro Magazzu +8
Recently, acoustic tweezers based on an array of ultrasonic transducers have been reported taking inspiration from holographic optical tweezers. In the latter technique, the calibr…
Investigation of dust grains by optical tweezers for space applications
A. Magazzù, D. Bronte Ciriza, A. Musolino +10
Cosmic dust plays a dominant role in the universe, especially in the formation of stars and planetary systems. Furthermore, the surface of cosmic dust grains is the bench-work wher…
Roadmap for Optical Tweezers
Giovanni Volpe, Onofrio M. Maragò, Halina Rubinzstein-Dunlop +80
Optical tweezers are tools made of light that enable contactless pushing, trapping, and manipulation of objects ranging from atoms to space light sails. Since the pioneering work b…
Epsilon-Near-Zero (ENZ)-based Optomechanics
Y. Kiasat, M. G. Donato, M. Hinczewski +6
Optomechanics deals with the control and applications of mechanical effects of light that stems from the redistribution of photon momenta in light scattering. Here, we investigate,…
Near-field imaging of surface-plasmon vortex-modes around a single elliptical nanohole in a gold film
Claudia Triolo, Salvatore Savasta, Alessio Settineri +4
We present scanning near-field images of surface plasmon modes around a single elliptical nanohole in 88 nm thick Au film. We find that rotating surface plasmon vortex modes carryi…
Electrospun Conjugated Polymer/Fullerene Hybrid Fibers: Photoactive Blends, Conductivity through Tunnelling-AFM, Light-Scattering, and Perspective for Their Use in Bulk-Heterojunction Organic Solar Cells
Zhenhua Yang, Maria Moffa, Ying Liu +10
Hybrid conjugated polymer/fullerene filaments based on MEH-PPV/PVP/PCBM are prepared by electrospinning, and their properties assessed by scanning electron, atomic and lateral forc…
Biomineral Amorphous Lasers through Light-Scattering Surfaces Assembled by Electrospun Fiber Templates
Maria Moffa, Andrea Camposeo, Vito Fasano +7
New materials aim at exploiting the great control of living organisms over molecular architectures and minerals. Optical biomimetics has been widely developed by microengineering,…
Spin-Momentum Locking in the Near Field of Metal Nanoparticles
Claudia Triolo, Adriano Cacciola, Salvatore Patanè +3
Light carries both spin and momentum. Spin-orbit interactions of light come into play at the subwavelength scale of nano-optics and nano-photonics, where they determine the behavio…
Localized surface resonances of J-aggregate nanostructures
Claudia Triolo, Adriano Cacciola, Omar Di Stefano +5
Metallic nanostructures are able to concentrate light into volumes far below the diffraction limit. Here we show, by accurate scattering calculations, that nanostructures obtained…
Brownian Motion of Graphene
O. M. Marago, F. Bonaccorso, R. Saija +9
We study the Brownian motion (BM) of optically trapped graphene flakes. These orient orthogonal to the light polarization, due to the optical constants anisotropy. We explain the f…
Quantum Electrodynamics of Quantum Dot-Metal Nanoparticles Molecules
A. Ridolfo, O. Di Stefano, N. Fina +2
We study theoretically the quantum optical properties of hybrid molecules composed of an individual quantum dot and a metallic nanoparticle. We calculate the resonance fluorescence…
