Paper Abstract

We report in this paper a theoretical analysis of some parameters which characterize the Er3+-doped Ti:LiNbO3 straight waveguide amplifiers. The derivation and the evaluation of the spectral optical gain, the spectral noise figure, the signalto- noise ratio and the amplified spontaneous emission photon number are performed under the small gain approximation taking into account the overlap between the pump, signal and dopant distribution profiles. In our simulations the Er3+- profile is considered erfc, Gaussian or constant in depth and Gaussian in width, with a surface concentration of about 7•1025m-3 and a diffusion depth of 20 μm.
