Optical tweezers with cylindrical vector beams produced by optical fibers

Gradient radiation forces exerted by strongly focused cylindrical vector beams of radial and azimuthal polarizations on dielectric spheres of different radii and refractive indices were calculated. The effect of longitudinal and transversal components of the focused electrical field on trapping properties was studied. Experiments on optical trapping were performed using low-mode optical fiber excited with Laguerre-Gaussian beam as a source of the trapping beams.
