Optical forces between metallic particles [PDF]
Proceedings of the National Academy of Sciences, 2005 We calculate the optical attractive forces that occur between 30-nm Au or Ag nanocrystals when irradiated at visible wavelengths. These forces show resonances at dipolar plasmon wavelengths, similar to resonances in the near-field electromagnetic intensities.

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.

Optical forces in nanorod metamaterial [PDF]
Scientific Reports, 2015 AbstractOptomechanical manipulation of micro and nano-scale objects with laser beams finds use in a large span of multidisciplinary applications. Auxiliary nanostructuring could substantially improve performances of classical optical tweezers by means of spatial localization of objects and intensity required for trapping.

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 ...

Lateral chirality-sorting optical forces [PDF]
Proceedings of the National Academy of Sciences, 2015 SignificanceIn light of the difficulty often associated with sorting and characterizing materials by chirality, new research aimed toward the development of passive optical methods has stirred considerable excitement at the interface of analytical chemistry and physical optics. We describe here a mechanism through which chirality-sorting optical forces
