WebAug 1, 2013 · There is a different kind of optical force other than gradient, scattering and curl force; known as the optical binding force [19–27], which can also be used as a powerful tool to precisely control the mutual attraction and repulsion between different objects for colloidal self-assembly, crystallization, and so on [27] without the need for … WebMar 26, 2015 · In optical binding, applied electromagnetic radiation not only traps but also induces a force between particles. These laser-induced forces can be either attractive or repulsive (despite the term “binding”) and, crucially, they may override the intrinsic dispersion force that acts between particles.

WebAug 25, 2024 · However, the optical interactions studied thus far only provide conservative optical binding forces of limited tunability. In this work, we exploit the phase coherence between the optical fields that drive the light-induced dipole-dipole interaction to couple two nanoparticles. ... The total light-induced interaction is a combination of a ... WebIn general, the optical binding force between identical particles is thought to be symmetric.

WebAug 13, 2024 · Near-field optical binding force is an emerging new topic in the field of optical manipulation and plasmonics. However, so far, all the studies of near-field binding force and its counterintuitive reversal are only restricted to dimer sets. In this work, we have studied extensively the idea of near-field optical binding force and associated Lorentz … WebAn optical tweezer uses forces exerted by a strongly focused beam of light to trap small objects. Although the theory of optical tweezing is still being developed, the basic … WebThe two optical torques are competing with each other. The net torque can be positive or negative depending on the lattice spacing. At the optical binding spacing, the = 7 . m channel has the dominant contribution to the transversely scattered light.
