All-dielectric silicon metalens for two-dimensional particle manipulation in optical tweezers

Abstract Generally, an optical vortex lattice (OVL) is generated via the superposition of two specific vortex beams. Thus far, OVL has been successfully employed to trap atoms via the dark cores. The topological charge (TC) on each optical vortex (OV) in the lattice is only ±1. Consequently, the orbital angular momentum (OAM) on the lattice is ignored. To expand the potential applications, it is necessary to rediscover and exploit OAM. Here we propose a novel high-order OVL (HO-OVL) that combines the phase multiplication and the arbitrary mode-controllable techniques. TC on each OV in the lattice is up to 51, which generates sufficient OAM to manipulate microparticles. Thereafter, the entire lattice can be modulated to desirable arbitrary modes. Finally, yeast cells are trapped and rotated by the proposed HO-OVL. To the best of our knowledge, this is the first realization of the complex motion of microparticles via OVL. Thus, this work successfully exploits OAM on OVL, thereby revealing potential applications in particle manipulation and optical tweezers.

Abstract As an indispensable complement to an integer vortex beam, the fractional vortex beam has unique physical properties such as radially notched intensity distribution, complex phase structure consisting of alternating charge vortex chains, and more sophisticated orbital angular momentum modulation dimension. In recent years, we have noticed that the fractional vortex beam was widely used for complex micro-particle manipulation in optical tweezers, improving communication capacity, controllable edge enhancement of image and quantum entanglement. Moreover, this has stimulated extensive research interest, including the deep digging of the phenomenon and physics based on different advanced beam sources and has led to a new research boom in micro/nano-optical devices. Here, we review the recent advances leading to theoretical models, propagation, generation, measurement, and applications of fractional vortex beams and consider the possible directions and challenges in the future.

Elastic Constraints

AbstractThe ATP-dependent motility of the kinesin-related non claret disjunctional (ncd) mechanoenzyme was observed in an in vitro bead motility assay using optical tweezers in combination with a new two-dimensional displacement detection method. The detection technique is based on observing the far-field interference pattern formed in the back focal plane (BFP) of the microscope condenser by the illuminating laser focus and the light scattered from the trapped dielectric bead. The ability to observe the two-dimensional motion, with high temporal and spatial resolution, and in a manner largely independent of position in the microscope field-of-view, is the particular advantage of this detection method. In the assay, a fusion protein (GST-N195) of truncated ncd and glutathione-Stransferase was adsorbed to silica beads and the axial and lateral motions of the beads along the microtubule surface were observed. The average axial velocity of the ncd coated beads was 230 ± 30 nm/s (± std. dev.). Spectral analysis of bead motion showed an increase in viscous drag near the surface. Furthermore, we also found that any elastic constraints of the moving motors are much smaller than the constraints due to binding in the presence of the non-hydrolyzable nucleotide adenylylimido-diphosphate (AMP-PNP).
