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.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
