AbstractWe demonstrate non-inverted wavelength conversion at 80Gb/s based on cross-phase modulation in a SOA. Using a flat-top 6nm broad filter with sharp roll-off we achieve a penalty of only 0.5dB IntroductionAll-optical wavelength converters (AOWCs) are likely to become essential building blocks for future dynamic high-capacity optical networks [ 1]. Semiconductor optical amplifiers (SOAs) have attracted considerable research interest for wavelength conversion due to their integration potential and power efficiency. Error-free wavelength conversion based on cross-gain and cross-phase modulation in a single SOA has been demonstrated at 320 Gb/s at the expense of a large penalty mainly caused by the excessive losses by a polarity inverter required for realizing non-inverted wavelength conversion [ 2]. It has been previously suggested [ 3] and demonstrated [ 4] that 80Gb/s direct non-inverted wavelength conversion can be achieved by filtering of only ...

Enhanced 40 and 80 Gb/s wavelength conversion using a rectangular shaped optical filter for both red and blue spectral slicing

“…Thus larger than required detuning of the filter's center frequency from the original CW probe signal was needed in order to obtain the suppression of the CW component resulting in large attenuation of the remaining spectral components and a poor Optical Signal to Noise Ratio (OSNR). Recently we have reported on the operation of an 80Gb/s WC with low penalty based on the same principle [7].…”
