Abstract

Optical traps using optical fibers can facilitate trapping, manipulation, and characterization of particles ranging from dielectric beads, through anisotropic particles such as rare-earth doped nanorods, with the added advantage of a small footprint. Here, we will introduce several fiber traps, including the quasi-Bessel beam optical fiber tweezers and the optical nanofiber, and illustrate the variety of measurements that can be made depending on the configuration chosen.
