Abstract

Based on optical methods in this paper we report some experimental and theoretical results concerning the evaluation of losses and group effective refractive index of Er3+:Ti:LiNbO3 optical waveguides from the transmitted intensity of the FabryPérot optical waveguide resonator. Using interferometric methods in order to obtain the resonances (heating the optical waveguide cavity with a Peltier element and also varying the frequency of a tunable laser) from the experimental data we evaluated the attenuation coefficient for a laser radiation having λ =1.55 μ m and also, from the same spectra the group effective refractive index.
