A broadband optical amplifier that can provide a constant amplifier gain profile, correct for ASE noise, and minimize gain tilt by dynamically controlling different stages of the amplifier through a combination of gain, loss, and power control of each stage depending on input and the desired output level. The multiple stage amplifier has a central control circuit independently controlling each stage, the amplifier comprising a plurality of sequentially coupled stages, each stage being an attenuator stage, a gain setting sub-amplifier stage, or a power level setting stage. The central control circuit determines which stages are actively gain or power controlled.
