摘要
Optical tweezers based on plasmonics experience a tremendous development on manipulating nanoparticles but are unable to avoid the problem of Joule heating. In this Letter, we report a silicon nanotrimer to optically trap and manipulate nanoparticles with negligible local heating. The optical forces and trapping potential of the nanotrimer are investigated using the finite-difference time-domain method. The results indicate that the trapping position can be shifted by tuning the polarization of the incident light. Furthermore, the silicon nanotrimer enables simultaneous trapping of multiple nanoparticles using circularly polarized illumination. Our work provides a promising building block for an integrated all-dielectric platform to realize optically driven nanomanipulation, which offers new possibilities for on-chip optical applications.
