Abstract
We have proposed and systematically studied a cascaded bowtie photonic crystal nanobeam system that can achieve multiplexed long-range electrohydrodynamic transport and optical trapping of nanoscale particles. Ultra-high quality factor and ultra-low mode volume has been demonstrated, providing a strong field gradient ideal for trapping sub-20 nm particles. Combined with an applied alternating current electric field, the localized water absorption induces the electrothermal flow that can efficiently transport nanoparticles to the vicinity of a given bowtie region by switching the input wavelength. We envision this system will be promising in many fields, including single molecule characterization and assembly of single photon emitters.
