Optical binding force

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. 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.
