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.

摘要： The invention relates to an optical component based on semi-conductor optical amplifiers in which the number of independent electrodes is reduced. The component has different regions (1, 2, 3, 4, 5) with the same vertical structure wherein an active waveguide (20) is buried between the upper and lower buffer layers. These regions each have lower and upper electrodes (10, E2, E4) for the purpose of injecting into them equal or different values of current density. This component is characterized in that at least one (10) of the said electrodes covers a number of regions (1, 3, 5) and has distributed resistivity which is adjusted depending on the region under consideration.

摘要： Aspects of the disclosure provide systems and methods which avoid the negative effects of Spectral Hole Burning when spectral changes are made for an optical communication system (OCS). 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 OCS. Embodiments include a configurable idle tone source for providing power to each of a set of idle tone wavelengths distributed across the spectral band used in the optical communication system. The configurable idle tone source is communicatively coupled to an output fiber of an optical network element and controlled such that optical power is present in the output optical fiber at each one of the set of idle tone wavelengths.

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.
