ALL-OPTICAL 1300-NM TO 1550-NM WAVELENGTH CONVERSION USING CROSS-PHASE MODULATION IN A SEMICONDUCTOR OPTICAL AMPLIFIER

All-optical 1300-nm to 1550-nm wavelength converters may be important components in lightwave networks which use both the 1300-nm and the 15 50-nm low-loss transmission windows of silica optical fiber. We descri be a new all-optical 1300-nm to 1550-nm wavelength converter, based on cross-phase modulation in a 1300-nm semiconductor optical amplifier. We demonstrate operation of the wavelength converter at 1.25 Gb/s, and present bit-error rate measurements, The wavelength converter demonst rated here potentially operates at high speed, with low input power an d low polarization-sensitivity.
