Photonic Hook Initiated Using an Air–Liquid Interface
Photonics, 2023 In this paper, we demonstrate a novel photonic hook being initiated using an air–liquid interface (ALI). This bent light focus is produced by immersing a dielectric micro-cylinder partially at the edge of a thin liquid film whose thickness is smaller ...

Sample dependence of the Casimir force [PDF]
, 2006 We have analysed available optical data for Au in the mid-infrared range which is important for a precise prediction of the Casimir force. Significant variation of the data demonstrates genuine sample dependence of the dielectric function. We demonstrate

Enhancement of optical force acting on vesicles via the binding of gold nanoparticles. [PDF]
R Soc Open Sci, 2019 Here we found that gold nanoparticles (AuNPs) enhance the optical force acting on vesicles prepared from phospholipids via hydrophobic and electrostatic interactions.

Polarization‐Dependent Optical Forces Arising from Fano Interference
Advanced Physics Research, 2023 A Fano resonance originates from the resonant coupling between interacting multipoles inside nanostructures. It breaks the symmetry of spectral line shape and enables Fano‐resonant media to present unusual scattering properties.

Optical force and torque on small particles induced by polarization singularities [PDF]
Optics Express 30, 16489 (2022), 2022 Optical forces in the near fields have important applications in on-chip optical manipulations of small particles and molecules. Here, we report a study of optical force and torque on small particles induced by the optical polarization singularities of a gold cylinder.

Actuation of Micro-Optomechanical Systems Via Cavity-Enhanced Optical Dipole Forces [PDF]
, 2007 We demonstrate a new type of optomechanical system employing a movable, micron-scale waveguide evanescently-coupled to a high-Q optical microresonator. Micron-scale displacements of the waveguide are observed for milliwatt(mW)-level optical input powers.
