Abstract

We present the suitability of the Third Harmonic Generation (THG) technique as a new nonlinear microprobe for non destructive determination of the index profile of new types of optical fibers and particularly for the test of Photonic Bandgap (Bragg type) and microstructured air-silica (MAS) fibers. The complete spatial characteristics such as hole diameter and spacing into MAS fibers or sandwiched layer thickness into Bragg fibers were demonstrated to be attainable anywhere along a bare fiber.
