Paper Abstract

In this paper we report some experimental and theoretical results concerning the characterization of the coupling between optical fibers and optical waveguides using nondestructive methods. The optical transmission method was used for the measurement of the optical attenuation in graded index profile optical fiber (&lgr;=0.63 &mgr;) and the resonator method for Ti:LiNbO3 optical waveguides (&lgr;=1.55 &mgr;). The refractive-index profiles of optical fibers characterized by a graded index profile and Ti:LiNbO3 optical waveguides has been determined for &lgr;=1.55 &mgr; from near field intensity measurement using a standard optical fiber as receiver. The obtained results are in good agreement with other obtained by several authors and can be used for the design of optical fiber sensors and optoelectronic integrated circuits.
