ith this erratum, we provide the corrected optical force map and optical potential for Figure 5. The grid resolution used in the original calculation was not sufficient to guarantee convergence. The grid spacing has been reserved to 5 nm, and the forces are now calculated with the bottom edge of the particle 5 nm above the surface of the slab. The forces are obtained from a volumetric integral of the Lorentz force, using the electromagnetic fields obtained from a finite-difference time domain simulation (Lumerical). This method allows smaller particle-slab separations than the Maxwell Stress Tensor method used previously. The corrected forces are shown in Figure 5a. The corrected in-plane potential is shown in Figure 5b,c. The minimum is at the center of the unit cell. The total potential, which includes the effect of sinking, also has a minimum at the center of the unit cell. The total potential is deeper than the in-plane potential. Shao-Hua Wu and Ningfeng Huang contributed to this correction. They were not authors on the original manuscript. N. H. identified the convergence issues in the original calculation. S.-H. W. carried out calculations and verified convergence.
Figure 5. Calculated optical forces and potentials. (a) Force map in one unit cell. The color bar represents the vertical optical force in dimensionless units of Fc/P, where c is the speed of light and P is the incident optical power. A negative force indicates attraction toward the slab. The arrows represent the magnitude of the lateral optical force. The length of the black arrow at the bottom center of the figure corresponds to the in-plane value of 1. (b) The potential through the center of the hole along the x-direction. (c) The potential through the center of the hole along the y-direction.
