Abstract

Recently, transformation optics is applicable in optofluidic research to realize novel photonic characteristics. Diffusion in the microfluidic channel realizes a gradient-index profile to manipulate light wave propagation through it, which is tunable and reconfigurable. In this paper, a pair of optofluidic parallel waveguide with nanogap is realized in the microchannel. By manipulating the diffusion process between the liquid flow streams, distinctive light propagation patterns are observed, including chirped coupling pattern in symmetrical waveguides and complex leaky lightwave in asymmetrical waveguides. With these distinctive lightwave patterns, single molecule sorting can be realized by using optical forces.
