Dual-curvilinear beam enabled simultaneous and tunable manipulation of light- and dark- seeking particles

- Abstract: We present an innovative approach for the agile manipulation of light- and dark-seeking particles. Our method involves introducing a dual-curvilinear optical vortex beam (DC-OVB) generated by superimposing a pair of curved beams. The proposed DC-OVB provides customizable motion paths and velocities for both dark-seeking and light-seeking particles. Each curve of the DC-OVB can support a distinct orbital flow density (OFD), enabling the application of torques to light- and dark-seeking particles, guiding them to orbit along specified trajectories. We conduct experimental manipulations on light- and dark-seeking particles, prompting them to execute various curvilinear motions simultaneously, including linear movement, revolution, and rotation.
