Paper Abstract

In the small gain approximation and the unsaturated regime in this paper we report some original results concerning the evaluation of the spectral optical gain, spectral noise figure and signal to noise ratio on the dopant concentration in Er3+-doped LiNbO3 straight waveguide pumped near 1484 nm using erfc, Gaussian and constant profile of the Er3+ ions in LiNbO3 crystal. We used a quasi-two-level model to simulate the optical amplification of Er3+-doped LiNbO3 straight waveguide amplifiers and we demonstrated that high gains (36,12 dB and 39,09 dB for erfc and Gaussian, respectively Er3+ - profiles in depth) and low noise figures (16.51 dB and 17.51dB) are achievable for 50 mW input pump power. The obtained results can be used for the design of the integrated optical devices.
