Locally Structured On-Chip Optofluidic Hollow-Core Light Cages for Single Nanoparticle Tracking

A waveguide system, which is locally structured to form on-chip optofluidic hollow-core light cages, is presented as a novel platform for waveguide-assisted nanoparticle tracking analysis. The mode behavior within the novel light cage is analyzed via measurements as well as simulations with JCMsuite.
