Abstract ：We propose a series of modified hybrid plasmonic waveguide systems. It is found that their propagation distances and mode areas depend on their shapes notably. The optical trapping forces exerting on the dielectric nanoparticles are calculated, and the strength and range of the forces can be adjusted by altering the shapes of the waveguides. These features demonstrate the possibility of using the modified hybrid waveguide systems to design tunable nanoscale optical tweezers.
