Abstract: 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.

Abstract: A method for controlling an optical amplifier is disclosed. The illustrative method includes inputting a set-point to a controller; receiving a portion of an input signal; receiving a portion of an output signal from a first amplifier stage; receiving a portion of an output signal from an attenuation stage; receiving a portion of an output signal from a second amplifier stage and adjusting the first amplifier stage, the second amplifier stage and the attenuation stage based on the received portions to substantially maintain the set-point. An optical amplifier includes a controller which receives a portion of an input signal, a portion of an output signal from a first amplifier stage, a portion of an output signal from an attenuations stage, and a portion of an output signal from a second amplifier stage. The controller adjusts the first amplifier stage, the attenuation stage, the attenuation stage, and the second amplifier stage based on the received portions of the signals.
