Abstract

Based on the small gain approximation in the unsaturated regime in this paper we present the derivation and the evaluation of the spectral optical gain, spectral noise figure and spectral quality factor on single and double pass configuration Er³⁺-doped LiNbO₃ waveguide amplifier pumped near 1484 nm. The simulations show the evolution of the above mentioned parameters under various pumping regimes. In the present work we demonstrated that high gains and low noise figures are achievable in high pump regimes and double pass configuration. The obtained results can be used to theoretically model the optical amplification around 1500 nm in Er³⁺-doped LiNbO₃ waveguides are function of various parameters.
