Abstract
The invention relates to an optical amplifying structure capable of amplifying at least one light wave S, comprising in a substrate, for each wave to be amplified, an amplifying assembly composed of: a first micro-waveguide (7) capable of receiving the light wave S to be amplified, a second micro-waveguide (9) capable of receiving a pumping wave L, a multiplexing device (11) associated with the first and second micro-waveguides, and capable of providing a coupled light wave composed of the wave S and the wave L, an amplifying device (13) connected to an output of the multiplexing device and capable of amplifying the light wave S by at least partial absorption of the pumping wave L, the amplifying device being capable of providing at one output the amplified light wave S. a third micro-waveguide (15) connected to the output of the amplifying device and capable of carrying the amplified light wave S, and a demultiplexing device (19) associated with the third micro-waveguide and capable of demultiplexing the pumping wave L from the amplified wave S, and of providing on a fourth micro-waveguide (17) an amplified light wave S, purged of the pumping wave. The structure of the invention is applied to all fields necessitating an amplification of a light wave and in particular in the field of optical telecommunications by optical fibres.
