An all-optical regenerating circuit including a wavelength converter based on a Mach-Zehnder interferometer. The input signal is amplified and the interferometer adjusted to place the input signal across an entire monotonic portion of a sinusoidal transfer function to the wavelength-converted output...http://www.google.fr/patents/US7099586?utm_source=gb-gplus-shareBrevet US7099586 - Reconfigurable multi-channel all-optical regenerators
