Abstract
An architecture for the handling and transport of nanoscopic matter in lab on a chip devices using optical forces. A slot waveguide is used to focus and harness optical energy to trap and transport nanoscale objects. The slot waveguide is a unique structure that has several advantageous features, such as high optical confinement, and enables nanoparticles to interact fully with a propagating optical mode.
