Szukana fraza: [Abstrakt = "Wavelength conversion based on the cross\-polarization modulation \(XPM\) in a single semiconductor optical amplifier \(SOA\) has been numerically investigated by using the theoretical model in which the birefringence has been taken into account. The results show that the non\-inverted and inverted wavelength conversion can be realized through selecting reasonably the parameters\; there exit some differences in the chirp, extinction ratio \(ER\), and eye diagram of the converted signal between the non\-inverted and inverted conversion\; with the increase of the bit rate, the chirp increases and the eye opening ratio \(EOR\) decreases."]
