Abstract

This paper reports some modelling results concerning a novel Er³⁺:Ti:LiNbO₃ optical waveguide directional coupler. Based on the mode coupling theory we evaluated the coupling coefficient between the straight and curved waveguides of the directional coupler. Also, using a quasi-two-level model 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 spectral signal-to-noise ratio in the bent Er³⁺:Ti:LiNbO₃ waveguide of the directional coupler pumped near 1484 nm performed for erfc, Gaussian and constant profile of the Er^3_ ions in LiNbO₃ crystal.
