Paper Abstract

In this paper we report some experimental and theoretical results concerning the evaluation of some spectroscopic parameters which characterize the Er3+ and Yb3+ doped LiNbO3 optical waveguide amplifiers. The transmission spectra were used to determine the homogeneous absorption and emission cross sections (utilizing the density matrix formalism and the McCumber's theory and taking into account the Stark splitting of the levels), the oscillator strength of the absorption transition, the spontaneous emission probabilities, radiative lifetime and the excitation energy in the near IR region of the optical spectrum: around 1530 nm and 980 nm, respectively. The obtained results are in good agreement with other ones published in the literature in the last few years and can be used for the theoretical modelling of the guided lasers and amplifiers, design of guided optoelectronic devices etc.
