Alternative configuration for refracted near-field measurements of refractive index on glass-integrated-optics waveguides.
We present experimental investigations of two configurations for refractive-index profiling and for geometry measurements of glass-integrated waveguides with the refracted near-field technique. An original configuration is proposed that simplifies the measurement cell and the handling.
