Abstract

The evanescent coupling effect between two nano-optofluidic waveguides is demonstrated and studied. The nano-optofluidic waveguides can be easily controlled and tuned by changing the flow rates of the four flow streams such that a nano-gap as small as 50 nm can be easily achieved. The evanescent coupling patterns under different conditions are analyzed to determine the nano-gap and the refractive index contrast of the nano-optofluidic waveguides. Novel and tunable photonic devices can be easily designed and realized by using the nano-optofluidic platform for biomolecular detection and manipulation applications.
