Paper Abstract

In this paper we report some experimental and theoretical results concerning the characterization of the Er 3+ :Ti:LiNbO3 and Ti:LiNbO3 optical waveguides using the near-field measurements at 1540 nm wavelength. The near-field measurements have been performed using a standard fibre probe for the scanning of the waveguide transversal section, but also an infrared vidicon camera. Using the Helmholtz scalar equation and a deconvolution procedure we evaluated some parameters which characterize Er 3+ :Ti:LiNbO3 waveguides: the refractive-index difference and the penetration depth. Also, we evaluated the coupling loss coefficients between a standard optical fibre and Ti:LiNbO3 and Er 3+ :Ti:LiNbO3 optical waveguides for λ =1.54 μm.
