Dynamic controller for a multi-channel optical amplifier |
| 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 (20) coupled between the two amplification coils (11 and 15) of the EDFA amplifier, and a control circuit (22) that instructs the attenuator (20) 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 (26 and 32) and a tilt controller (52) connected to the control circuit (22) 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. |
