Abstract:
An optical amplifier comprising:a first amplification stage configured to be coupled to an optical communication path, said amplification stage receiving a plurality of optical signals, each of which being at a respective one of a plurality of wavelengths said first amplification stage having an associated first optical gain and outputting said plurality of optical signalsa dispersion compensating element coupled to said amplification stage and receiving said amplified plurality of optical signals, said dispersion compensating element further having an associated second optical gain and outputting said plurality of optical signals; anda second amplification state receiving said plurality of optical signals from said dispersion compensating element, said second amplification stage having an associated third optical gain, said associated second optical gain being adjusted so that said plurality of optical signals output from said optical amplifier have substantially uniform optical gain.
