摘要：
The present invention provides a cross-gain modulation type optical wavelength converter having a high extinction ratio and a wide input dynamic range, which is capable of preventing an extinction ratio from lowering and allowing an input dynamic range to widen. The XGM type optical wavelength converter of the present invention allows a probe light to be cross-gain modulated by a pump light one more time using two SOAs, and allows the width of the modulation of the probe light to be further broadened, thereby improving the extinction ratio after wavelength conversion. Simultaneously, the XGM type optical wavelength converter detects the intensity of an optical signal inputted to the optical wavelength converter and automatically controls the intensity of the probe light on the basis of the detected intensity of the input optical signal, thereby providing a wide input dynamic range.
