Liquid Waveguide-Based Evanescent Wave Sensor That Uses Two Light Sources with Different Wavelengths

We demonstrate a prototypic optofluidic evanescent wave sensor made of poly(dimethylsiloxane) (PDMS) elastomer in which two light sources with different wavelengths are coupled into an optofluidic liquid-core/liquid-cladding (L2) waveguide. The exponentially decaying evanescent wave interacts with a...
