    • An optical amplifier includes an optical feedback resonant laser cavity (OFRC) including a power dependent loss element (PDLE) having the characteristic that as the incident laser power on the PDLE increases the cavity loss decreases. The OFRC with the PDLE provides optical gain control or optical power control for a WDM amplifier or a single channel power equalization amplifier (PEA), respectively. A 1×N×N WADM node incorporating more than one of these amplifiers, at least some of which commonly share a pump source, and a method for controlling a transient power change in a single channel optical amplifier or reducing a DC gain error in a WDM optical amplifier that are subject to dynamically variable operating conditions at an input of the amplifier, are also disclosed.
    • 光放大器包括光反馈谐振激光腔(OFRC),其包括功率依赖损耗元件(PDLE),其特征在于,随着PDLE上的入射激光功率增加,空腔损耗减小。 OFRC与PDLE分别为WDM放大器或单通道功率均衡放大器(PEA)分别提供光增益控制或光功率控制。 包括这些放大器中的多于一个的1xNxN WADM节点,其至少一些通常共享泵浦源,以及用于控制单通道光放大器中的瞬态功率变化或减少WDM光放大器中的DC增益误差的方法, 在放大器的输入处经受动态可变的工作条件。

    • A dynamic controller for a multi-channel EDFA-type optical amplifier is provided that is capable of providing a substantially tilt-free output over a range of selectable gain set points. The dynamic controller includes a variable optical attenuator coupled between the two amplification coils of the EDFA amplifier, and a control circuit that instructs the attenuator of an amount that each channel should be attenuated to achieve a tilt-free output at a selected gain point. The controller further includes a gain controller and a tilt controller connected to the control circuit of the variable optical attenuator for providing signals indicative of an average amount of per channel attenuation and a relative amount of per channel attenuation necessary to achieve a selected gain set point while reducing or eliminating tilt, respectively.
    • 提供了一种用于多通道EDFA型光放大器的动态控制器,其能够在可选择的增益设定点的范围上提供基本无倾斜的输出。 动态控制器包括耦合在EDFA放大器的两个放大线圈之间的可变光衰减器,以及控制电路,其指示衰减器的衰减量,每个通道应被衰减以在选定的增益点实现无倾斜输出。 控制器还包括增益控制器和连接到可变光衰减器的控制电路的倾斜控制器,用于提供指示平均每通道衰减量的信号以及实现所选增益设定点所必需的每通道衰减的相对量, 分别减少或消除倾斜。
