Novel all-optical noise suppressors based on the nonlinear transfer function properties of monolithically integrated active waveguide interferometers are proposed and demonstrated. Through a power map imbalance between the two arms of the interferometers, each of which contains multi-contact semiconductor optical amplifiers, a nonlinear transfer function is created, which can then be exploited to...
WDM multi-casting is experimentally demonstrated by performing all-optical simultaneous multi-wavelength conversion at 10 Gb/s and 40 Gb/s using a hybrid integrated Mach-Zehnder interferometer. At 40 Gb/s a Q factor degradation smaller than 0.63 was obtained for all channels
