It came as quite a surprise to the researchers in Vienna when they saw a completely different... WebFeb 1, 2016 · (a) Optical binding forces on a gold or silver homodimer (r =50 nm), and (b) lateral optical forces for rotating dimer versus distance as irradiated by LP plane waves with various θ (0°, 45°, and 90°) at λ =800 nm. Solid lines: gold dimer. Dotted lines: silver dimer.
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. Therefore, our optical matter arrays rotate in an opposite direction compared to the polarization WebApr 22, 2016 · We report optical trapping and assembling of colloidal particles at a glass/solution interface with a tightly focused laser beam of high intensity. It is generally believed that the particles are gathered only in an irradiated area where optical force is exerted on the particles by laser beam.
WebWe present calculations of the optical force on heterodimer of two gold nanorods aligned head-to-tail, under plane wave illumination that is polarized along the dimer axis. It is found that near the dipole-quadrupole Fano resonance, the optical binding force between the nanorods reverses, indicating an attractive to repulsive transition. 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 …
WebAug 6, 2024 · Optical binding of microparticles offers a versatile playground for investigating the optomechanics of levitated multi-particle systems. We report millimeter-range optical binding of polystyrene microparticles in hollow-core photonic crystal fiber. The first particle scatters the incident LP01 mode into several LP0n modes, creating a beat pattern that …
