Abstract :
We present a technique based on integrated optics to generate an evanescent wave illumination at the surface of a waveguide. This evanescent wave illumination is used to make velocity measurements within the first 80 nanometers of the waveguide surface using Nano-Particle Velocimetry (nPIV).
