Optofluidic Transport - Optical Waveguides as Microfluidic 'Train Tracks'

摘要

In this work we demonstrate optofluidic [1] transport and trapping of dielectric particles using the intense electromagnetic energy in the evanescent field of optically excited microphotonic waveguides. A conceptual overview of the transport mechanism is presented along with the detailed optofluidic theory which describes the transport. Experimental results for straight and curved waveguides are presented along with details of our experimental technique. The final section details our recent work on developing a stability condition for this form of transport.
