Description:
A Raman amplifier structure (121, 221) for optically amplifying an input optical signal comprises an optical means (22) through which the optical signal is propagated, a first pump optical source (10) for generating a first pump radiation and at least one second pump optical source (24, 27) for generating a second pump radiation. The first and second pump optical radiations are combined and propagated in optical transmission means (22) for supplying an optical amplification of the signal through the Raman effect. The first pump ...
