| Abstract(in English) | A CW assist light is useful for reducing gain recovery time and for suppressing the pattern effect in wavelength conversion based on the cross-gain modulation (XGM) using a semiconductor optical amplifiers (SOAs). The assist light is usually injected into the SOA under the transparent point of the gain curve since it can accelerate carrier recovery with a small gain reduction. However, the optimum condition for the assist light seems to vary for propagation directions, input power as well as wavelength because the transparent wavelength depends on the carrier density and its distribution inside the SOAs. In this paper, we clarify how the wavelength and propagation directions of the assist light influence the response of the converter both analytically and experimentally. We also study the optimization of the assist light conditions. |
