Abstract

Dynamic simulation is a powerful tool to observe the behavior of arbitrary shaped particles trapped in a focused laser beam. Here we develop a method to find equilibrium positions and orientations using dynamic simulation. This general method is applied to micro- and nano-cylinders as a demonstration of its predictive power. Orientation landscapes for particles trapped with beams of differing polarisation are presented. The torque efficiency of micro-cylinders at equilibrium in a plane is also calculated as a function of tilt angle. This systematic investigation elucidates in both the function and properties of micro- and nano-cylinders trapped in optical tweezers.

Trajectories of a glass microcylinder with D = 500 nm and L = 2000 nm in a linearly polarized beam. AB is starting position and orientation of the microcylinder, A2B2 is the trapped position and final orientation. The starting positions are (a) (−0.5, 0.5, −0.5)λ, (b) (0, 1, 0)λ, (c) (0.5, −0.5, −0.5)λ and (d) (−0.5, 0, 1)λ. The initial orientations are (a) (90°, 90°), (b) (45°, 270°), (c) (0°, 0°) and (d) (45°, 180°). The solid curve and arrow show the trajectory of one top center of the cylinder. The cylinder was finally trapped vertically at (0, 0, 0.94) λ (Media 1).

Rotations and translations of beam coefficients from initial Cartesian coordinate system x1y1z1 to an arbitrary coordinate system x3y3z3 through translated coordinate system x2y2z2. (A) and (B) are translations of beam coefficients along O1O2 direction. R1 and R2 are rotations of beam coefficients.

Trajectories of a simulated glass nanowire with D = 50 nm and L = 2000 nm in (a) linearly and (b) circularly polarized beams. AB is initial position and orientation of the nanowire, A2B2 is the trapped position and orientation. The solid curve and arrow show the trajectory of one top center of the cylinder. The linear polarisation contributed to the horizontal torque component which would make the nanowire lie down. But the circular polarisation made the time-averaged horizontal torque component so weak that the nanowire could stand up.

Orientations landscapes of nanowires and microcylinders in (a) linearly polarized and (b) circularly polarized beams. The coordinate system is Cartesian coordinate system centred at cylinder position. The rectangular shapes in (a) show the orientations of cylinders in each region. Four regimes in the orientation landscapes are the untrapped region, vertical region, horizontal region, and the intermediate region between the vertical and horizontal regions. The “circle” means the longest nanowire or microcylinder trapped horizontally for each diameter. The “asterisk” represents the shortest nanowire or microcylinder trapped vertically for each diameter. The “star” indicates the longest nanowire or microcylinder for each diameter, which can be trapped (vertically). The fitting curves are used to distinguish different regions.
