Optical particle sorting on an optofluidic chip

Kaelyn D. Leake, Brian S. Phillips, Thomas D. Yuzvinsky, Aaron R. Hawkins, and Holger Schmidt

We report size-based sorting of micro- and sub-micron particles using optical forces on a planar optofluidic chip. Two different combinations of fluid flow and optical beam directions in liquid-core waveguides are demonstrated. These methods allow for tunability of size selection and sorting with efficiencies as high as 100%. Very good agreement between experimental results and calculated particle trajectories in the presence of flow and optical forces is found.
