<p>The invention concerns an optical amplification system comprising an optical amplifier (AO) having an input (2) and an output (3) and amplifying wavelengths included in a first wavelength range. It comprises an optical coupling device (D) including: a first access (1') receiving a first optical wave (sμ1) in a second wavelength range included in the first wavelength range; a second access (4') receiving a second optical wave (sμ2) in a third wavelength range also included in the first wavelength range; an output (2') coupled with the optical amplifier (AO) input (2); an input (3') coupled with the optical amplifier (AO) output (3). Said device thus enables: directing the first optical wave (sμ1) from the first access (1') to the device output (2'); directing the amplified optical wave (Sμ1) resulting from the first optical wave amplification, from the coupling device input (3') to the second access (4'); directing the second optical wave (sμ2) from the second access (4') to the coupling device output (2'); directing the amplified optical wave (sμ2) resulting from the amplification of the second optical wave, from the coupling device input (3') to the first access (1').</p> |
