Abstract

We present the efficient implementation of phase sensitive-optical low-coherence interferometry to evaluate key performances (like dispersion law, coupling coefficient, optical losses, etc.) of photonic devices in general, and in particular of components based on optical micro-resonators, for both transverse electric and magnetic polarizations. Our setup was used for the characterization of vertically-coupled polymer micro-racetrack resonators. A mathematic model was developed to enhance the reliability of theoretical fitting to experimental curves, by taking into account first-order dispersion in the device under test.
