Abstract
The field of optofluidics involves the ability to manipulate fluids using light or to manipulate light using fluids, and is heavily integrated with the lab-on-a-chip concept. The biggest challenge is controlling the flow of liquid and propagation of light through the devices. A liquid core waveguide is a waveguide in which light propagates through the liquid, which is encapsulated in a material with a lower index of refraction. The difference in refractive indices leads to total internal reflection, enabling propagation through a long distance with low loss. In addition to minimizing loss, it is also important to control individual particles in a fluid. In the Ultrafast Nanoscale Optics group, we have developed a device capable of controlling the flow and placement of nanoparticles by using electrokinetic forces. The liquid core waveguides fabricated in our group, along with the particle controlled microfluidic chip, have potential to make a significant impact in the field of biophotonics and nanoplasmonics.
