    摘要： An optical signal regeneration device having an interferometric structure with two arms. Each of the arms has a medium, the optical power output of which is variable with the optical power input. The first arm receives, through an input coupler, a continuous wave and the signal to be regenerated. The second arm receives through the input coupler, a continuous wave signal and a clock signal. A filter, centered on the continuous wave wavelength, receives the output signal of the interferometric structure through the coupler. The filter output signal constitutes the regenerated 3R signal.

    摘要： To format a power modulated input optical signal, at the same time as improving its power dynamic range and the extinction rate of the output signal, a device for formatting binary optical signals includes a first stage for supplying a modulating signal having stabilized high levels as a function of the input signal and an interferometer structure second stage receiving the modulating signal and a probe wave power modulated in phase opposition to the modulation of the modulating signal. The low and high levels of the probe wave are stabilized. Applications include optical transmission.

    摘要： A method of managing an optical communications network comprising a plurality of nodes interconnected by optical sections. The method comprises: identifying one or more pairs of adjacent DL-equipped nodes at which dummy light (DL) hardware is deployed, respective dummy light (DL) hardware being deployed at fewer than the plurality of the nodes of the optical communications network, the respective DL hardware deployed at a particular node configured to supply dummy light to each optical section extending from the particular node, and defining a respective single-section DL path between each identified pair of adjacent DL-equipped nodes; identifying one or more pairs of non-adjacent DL-equipped nodes at which DL hardware is deployed, and defining a respective multi-section DL path between each identified pair of non-adjacent DL-equipped nodes; and causing the deployed DL hardware to supply DL light to each of the single- and the multi-section DL paths.

    摘要： Aspects of the disclosure provided systems and methods which mitigate negative effects of Spectral Hole Burning when spectral changes are made. Embodiments of the disclosure are directed to methods and systems which preform spectral holes for the range of wavelength channels expected to be used in the optical communication system. In some embodiments this is achieved by controlling the network to ensure optical power is provided at each of a set of idle tone wavelengths distributed across the spectral band used in the optical communication system. In some embodiments a routing and spectrum assignment function satisfies new service requests while maintaining power to the set of idle tone wavelength functions. In some embodiments a network control function configures Reconfigurable Optical Add/Drop Multiplexers to broadcast idle tone wavelengths to provide power to each idle tone in each section.
