Abstract
In order to improve the coupling efficiency of semiconductor optical amplifiers to single-mode fibers, a model of tapered-rib semiconductor optical amplifier is presented in this paper. The effects of the refractive index of the waveguide region and the structure of tapered-rib waveguide on the expanded output-mode of tapered-rib waveguide are studied and calculated by using the finite element method. A coupling efficiency of 95% is obtained by optimizing the parameters and the structure of the tapered-rib semiconductor optical amplifier.
