Abstract

A method for amplifying a time-varying optical signal comprising the steps of: generating an auxiliary optical signal the amplitude of which is chosen to be complementary to at least the envelope of the amplitude of the optical signal, superimposing the auxiliary optical signal to the optical signal resulting in a compound signal having an amplitude which is constant at least on average, amplifying the compound signal, and removing the amplified auxiliary optical signal from the amplified compound signal; as well as an optical amplification unit for carrying out the method.
