Abstract
Abstract The gain of the amplifier is stabilised by making the amplifier oscillate at a wavelength not used for amplifying the input signal (Pi). One illustrative embodiment comprises: - a substrate (2); - an active optical guide (waveguide) (3); - a grating (4) coupled along the entire length of the optical guide (3) and having a Bragg wavelength which is different from the wavelength of the signal to be amplified; - two electrodes (1, 6) for transversely injecting an electric current (I). Application to systems for transmitting optical signals. <IMAGE>
