摘要：
We describe an interferometric method that uses an interference microscope that permits the determination of the complete two-dimensional refractive-index profile of integrated optical waveguides, provided that the form of the one-dimensional depth profile is known. Results are reported for potassium-sodium ion-exchanged channel waveguides and are shown to be in good agreement with theory.
