Abstract
The improved characteristics of semiconductor optical amplifiers (SOAs) with optical pumping near the transparency (OPNT) are evaluated, and its improving mechanisms are analyzed. The characteristics of saturation behaviors, noise figures, signal-to-noise ratio, and gain recovery time are greatly improved by OPNT, especially for the counterpropagating scheme. The impacts of different wavelengths of a holding beam from absorption to the gain region are investigated contrastively. The maximum value of the small signal gain recovery time is obtained at the transparency wavelength. Also, the quality of the output eye patterns of a cross-gain modulation (XGM) system has been greatly improved by using OPNT, especially for the signal beyond
