Abstract

Transformation optics (TO) is a new method to design metamaterials that can manipulate electromagnetic fields. Different from the traditional TO technique which is mostly based on the solid metamaterials with a limited range of tunability, a novel transformation optofluidics (TOF) method is proposed to manipulate the light path by changing the streamlines of the flow in a circular bounded domain. A dipole flow model was built for the first time to analytically calculate the streamlines of a liquid core/liquid cladding (L²) configuration inside the domain. Experiment show that the light paths agree well with the theoretical models and have a large range of tunability for any optical source-sink pair locations and flow rate ratio of two cladding fluids.
