Abstract

Based on the transmission spectra of Er³⁺-doped LiNb0₃ optical waveguides in this paper we report some experimental and theoretical results concerning the evaluation of some spectroscopic parameters which characterize the above mentioned waveguides. The absorption experimental spectra were used to determine the homogeneous absorption and emission cross sections, the oscillator strength of the absorption transition, the spontaneous emission probabilities, radiative lifetime and the excitation energy in three regions of the optical spectra: around 1550 nm, 980 nm and 550 nm, respectively. The obtained results can be used for the design of optical guided lasers, amplifiers and other optoelectronic devices.
