摘要： An optical amplifier having an optical waveguide structure which includes a first region in which a first dopant (for example, Er) is doped in a first glass composition (for example, Al--Si glass) and a second region in which a second dopant (for example, Er) and a third dopant (for example, Yb) are doped in a second glass composition (for example, Al--P--Si glass). The first dopant is pumped so that the optical waveguide structure may provide a first gain characteristic determined by the first glass composition and the first dopant. The third dopant is pumped so that the optical waveguide structure may provide a second gain characteristic determined by the second glass composition and the second dopant. By selectively obtaining the first and second gain characteristics, where the optical amplifier is applied to WDM (wavelength division multiplexing), the output powers of optical signals of different channels can be controlled independently of each other.

摘要： A signal light passes through an isolator, and is coupled by a coupler with a pump light from a pump light source. Then, the signal light passes through an ASE reflection filter, is amplified by an EDF, and is transmitted from an isolator. At this time, an ASE light having a predetermined wavelength among ASE lights that occur within the EDF and proceed to the ASE reflection filter is reflected and again input to the EDF. By setting the predetermined wavelength to a wavelength on the short wavelength side of an amplification band of the EDF, gain deviation occurring on the long wavelength side of the amplification band can be cancelled.

摘要： A wavelength division multiplexed (WDM) optical signal amplifier which amplifies optical signals having different wavelengths with minimized deviations in their respective output power levels, while maintaining the total optical output at a constant power level. An optical splitter, disposed at the output of the amplifier, splits off a fraction of the amplified WDM optical output signal for feedback purposes. This WDM optical feedback signal is subjected to a wavelength division demultiplexer, where the optical components contained in the signal are demultiplexed into separate optical feedback signals each having a different wavelength. A plurality of optical power level detectors detect the optical power levels of the individual optical feedback signals. Based on the detected optical power levels, a controller adjusts the individual output power levels of the plurality of electrical-to-optical converters, so that the optical power levels detected by the optical power level detectors will coincide with each other.

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.

摘要： A contrivance, if a WDM signal state changes, is to improve an optical transmission quality by compensating gain flatness. A first excitation control unit sets a first optical pumping light source unit to emit excitation power needed to get the same amplifying operating level of a first amplifying medium as at the time of a maximum wavelength count when allocating wavelengths after a change in wavelength count at an equal interval in a wavelength range. A wavelength allocation bias estimation unit compares a present monitor value of optical power after outputting of a gain equalizer 13 with wavelength equi-allocation power associated with the recognized wavelength count, and thus estimates a wavelength allocation bias occurred as a concomitant of the change in the wavelength count. A primary gradient calculation unit obtains a primary gradient quantity defines as a gain deviation from the wavelength allocation bias. A second excitation control unit sets, in a second optical pumping light source unit, the excitation power needed to cancel the primary gradient quantity. An attenuation quantity control unit controls a variable optical attenuator to fix a gain by compensating an amount of change in the sum of gains.
