摘要： Optical systems of the present invention include a plurality of optical processing nodes in optical communication via at least one signal varying device. The signal varying devices includes an optical fiber suitable for facilitating Raman scattering/gain in a signal wavelength range and a pump energy source for providing pump energy in a plurality of pump wavelengths. The pump source provides sufficient pump energy in each pump wavelength to stimulate Raman scattering/gain in the optical fiber within the signal wavelength range. The pump wavelengths are selected such that the combined Raman gain resulting from the pump energy supplied by each pump wavelength produces a desired signal variation profile in the signal wavelength range. In addition, the pump energy supplied by at least one of the pump wavelengths can be varied to produce a controlled signal intensity variation profile over the signal wavelength range in the optical fiber.

摘要： 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.
