Based on the transmission and emission experimental spectra of Er 3+ -doped Ti:LiNbO3 optical waveguides in this paper we report some experimental and theoretical results concerning the evaluation of the real and imaginary parts of the complex atomic susceptibility of the above mentioned waveguides in the visible and near IR spectral range. The absorption and emission experimental spectra were used to determine the homogeneous absorption and emission cross sections (utilising the density matrix formalism and the McCumber's theory and taking into account the Stark splitting of the levels) around 1550 nm, 980 nm and 550 nm, respectively and finally for the evaluation of the complex atomic susceptibility.

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.
