Subfemtonewton force fields measured with ergodic Brownian ensembles
Minghao Li, Oussama Sentissi, Stefano Azzini +3
We demonstrate that radiation pressure force fields can be measured and reconstructed with a resolution of fN (at a confidence level) using an ergodic ensemble of ov…
Thermally limited force microscopy on optically trapped single metallic nanoparticles
Gabriel Schnoering, Yoseline Rosales-Cabara, Hugo Wendehenne +2
We propose and evaluate a new type of optical force microscope based on a standing wave optical trap. Our microscope, calibrated in-situ and operating in a dynamic mode, is able to…
Cross density of states and mode connectivity: Probing wave localization in complex media
Antoine Canaguier-Durand, Romain Pierrat, Rémi Carminati
We introduce the mode connectivity as a measure of the number of eigenmodes of a wave equation connecting two points at a given frequency. Based on numerical simulations of scatter…
Three-dimensional enantiomeric recognition of optically trapped single chiral nanoparticles
Gabriel Schnoering, Lisa V. Poulikakos, Yoseline Rosales-Cabara +3
We optically trap freestanding single metallic chiral nanoparticles using a standing-wave optical tweezer. We also incorporate within the trap a polarimetric setup that allows to p…
Plasmonic lateral forces on chiral spheres
Antoine Canaguier-Durand, Cyriaque Genet
We show that the optical force exerted on a finite size chiral sphere by a surface plasmon mode has a component along a direction perpendicular to the plasmon linear momentum. We r…
A chiral route to pulling optical forces and left-handed optical torques
Antoine Canaguier-Durand, Cyriaque Genet
We analyze how chirality can generate pulling optical forces and left-handed torques by cross-coupling linear-to-angular momenta between the light field and the chiral object. In t…
Chiral near fields generated from plasmonic lattices
Antoine Canaguier-Durand, Cyriaque Genet
Plasmonic fields are usually considered non-chiral because of the transverse magnetic polarization of surface plasmon modes. We however show here that an optical lattice created fr…
Transverse spinning of a sphere in a plasmonic field
Antoine Canaguier-Durand, Cyriaque Genet
We evaluate optical forces and torques induced by a surface plasmon to a sphere of arbitrary size, i.e. beyond the point-like dipolar limit. Through a multipolar decomposition of t…
Mechanical separation of chiral dipoles by chiral light
Antoine Canaguier-Durand, James A. Hutchison, Cyriaque Genet +1
We calculate optical forces and torques exerted on a chiral dipole by chiral light fields and reveal genuinely chiral forces in combining the chiral contents of both light field an…
Force and torque on an electric dipole by spinning light fields
Antoine Canaguier-Durand, Aurélien Cuche, Cyriaque Genet +1
We calculate the optical force and torque applied to an electric dipole by a spinning light field. We find that the dissipative part of the force depends on the orbital energy flow…
