Dan Dan Yang, Marc M Dignam: Input independent tilt free actively gain flattened broadband amplifier. JDS Uniphase, Neil Teitelbaum, April 10, 2001: US06215584 (16 worldwide citation)

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 ...
