摘要： An optical amplifying apparatus which includes an optical amplifier, an optical attenuator and a controller. The optical amplifier amplifies a light signal having a variable number of channels. The optical attenuator passes the amplified light signal and has a variable light transmissivity. Prior to varying the number of channels in the light signal, the controller varies the light transmissivity of the optical attenuator so that a power level of the amplified light signal is maintained at an approximately constant level that depends on the number of channels in the light signal prior to the varying the number of channels. While the number of channels in the light signal is being varied, the controller maintains the light transmissivity of the optical attenuator to be constant. Subsequent to varying the number of channels in the light signal, the controller varies the light transmissivity of the optical attenuator so that a power level of the amplified light signal is maintained at an approximately constant level that depends on the number of channels in the light signal subsequent to the varying the number of channels.

摘要： A device comprising an optical amplifier including an optical amplifying medium, and first and second optical filters operatively connected to the optical amplifier to suppress the wavelength dependence of gain. The medium has an input end and an output end for an optical signal. The medium is pumped so that it provides a gain band. The gain band includes a first band giving a relatively high gain and noise figure to the optical signal and a second band giving a relatively low gain and noise figure to the optical signal. The first optical filter is connected to the input end of the medium and has characteristics such that the first optical filter suppresses the wavelength dependence of gain in the second band. The second optical filter is connected to the output end of the medium and has characteristics such that the second optical filter suppresses the wavelength dependence of gain in the first band. This configuration allows suitable suppression of the wavelength dependence of gain in each optical filter, thereby providing a low noise figure and high optical output power.

摘要： An apparatus which receives an input light having a spectrum, and determines a momental wavelength of the spectrum. The apparatus includes a decoupling unit, a weighting unit and a computation unit. The decoupling unit decouples a portion of the received input light, to provide a first signal representing the input light with the portion decoupled therefrom, and a second signal representing the decoupled portion. The weighting unit weights the second signal. The computation unit determines the momental wavelength from the power of the first signal and the power of the weighted second signal. An optical amplifier is also provided which determines the momental wavelength of an amplified light, and controls a gain tilt parameter of the optical amplifier in accordance with the determined momental wavelength, to reduce gain tilt. An optical communication system is also provided which includes a plurality of such optical amplifiers sequentially arranged along an optical transmission line.

摘要： An optical amplification device which includes first and second optical amplifiers, and a controller. The first optical amplifier receives a light and amplifies the received light. The second optical amplifier receives the light amplified by the first optical amplifier, and amplifies the received light. When a level of the light received by the first optical amplifier changes by Δ, the controller controls a level of the light received by the second optical amplifier to change by approximately −Δ. In various embodiments, the controller causes the sum of the gains of the first and second optical amplifiers to be constant. In other embodiments, the optical amplification device includes first and second optical amplifier and a gain adjustor. The gain adjustor detects a deviation in gain of the first optical amplifier from a target gain, and adjusts the gain of the second optical amplifier to compensate for the detected deviation.
