Optical pulling forces and their applications
WebThe method of force tracing is employed to examine the optomechanical interaction between two and four Luneburg lenses. Using a simplified analytical model, as well as a realistic numerical model, the dynamics of elastic and fully inelastic collisions between the lenses under the illumination of collimated beams are studied. WebAfter a concise theoretical overview of the physical origins of optical forces, we describe how these forces can be harnessed to guide particles either in continuous bulk media or in the proximity of a constraining interface under various configurations of the illuminating light beams (radiative, evanescent, or plasmonic fields).
