Ignoring the amplified spontaneous emission(ASE), the gain characteristics of erbium doped silica optical waveguide amplifiers pumped at 980 nm wavelength are studied taking hydroxyl and upconversion into consideration.The effects of hydroxyl,upconversion and erbium concentration on gain are discussed in detail.Numerical results demonstrate that the optimization of the above parameters is very important for the improvement of the amplifiers gain.
