## Abstract Based on crossโgain modulation (XGM) in cascaded semiconductor optical amplifiers (SOAs), allโoptical AND and NOR operations at 20 Gb/s were both realized in the same configuration. By controlling the input signal power, the two logic gates can be achieved from different output channels
## Abstract A novel allโoptical logic OR gate based on crossโgain modulation (XGM) using a twoโcascaded semiconductor optical amplifiers (SOAs) in a counterpropagating topology is presented. The attractive issue of the proposed method is that the logic OR gate can be obtained at a probe wavelength
