Prototype of AFMOTs within the palm of a hand (a) and its close-up views (b,c). The fibers are located in the yz plane. (d) Schematic of the optical beam configuration at the trap. (e) Working principles of a 3D trap and particle deformation. The white arrows and the red envelopes stand for the direction and the magnitude, respectively, of the radiation pressure (optical stress), applied on the particle surface. The fibers in the system photos and schematics are cleaved single-mode optical fibers at 980 nm.
