Mode-dependent Emission Thresholds and Frequencies in Metal Nanoparticles within Gain-enhanced Media
Karen Caicedo, Nicole Recalde, Milena Mora +5
We present a mode-resolved analysis of emission thresholds in metal nanoparticles embedded within an infinite gain medium, using Mie scattering theory as a rigorous framework. Focu…
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…
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,…
Rotational dynamics of optically trapped polymeric nanofibers
Antonio Alvaro Ranha Neves, Andrea Camposeo, Stefano Pagliara +7
The optical trapping of polymeric nanofibers and the characterization of the rotational dynamics are reported. A strategy to apply a torque to a polymer nanofiber, by tilting the t…
