Abstract
Optical systems of the present invention include first and second optical amplifiers that are operated individually to provide gain profiles that do not conform with a desired composite, or overall or total, gain profile, e.g., substantially flat, but to produce a desired composite noise figure profile, e.g., substantially flat or otherwise, for the amplifiers. Generally, the desired composite noise figure profile is produced, while attempting to minimize the deviation of the composite gain profile from the desired composite gain profile.
