Abstract:
Optical tweezing is an emerging application of plasmonic nanostructures that aims at the exploitation of the enhanced light-matter interaction to trap nano-objects for sensing, biosensing, and spectroscopy purposes. In this contribution, we report the numerical analysis of efficient tweezing of subwavelength nanoparticles with radii smaller than 50 nm, in localized surface plasmon nanoantennas strongly coupled with Silicon on Insulator (SOI) waveguides. This integrated scheme ensures an intense excitation of the plasmonic resonators. Moreover, the dimer-like topology of the plasmonic nanoantenna further enhances the nearfield, leading to an ultra-efficient trapping.
