CA 2110191

In an optical amplification system of the present invention, an ASE (amplified spontaneous emission) light included in a signal light band is removed to provide low noise characteristics. The signal light is amplified by an optical amplification unit, and is supplied to an ASE removal unit. In the ASE unit, the signal light is transmitted therethrough, and the ASE light is reflected in the orthogonal direction to the light propagation direction. Consequently, the optical amplification system having low noise characteristics is obtained.

Dans un système amplificateur optique, une lumière d'émission spontanée amplifiée incluse dans une bande de signaux lumineux est retirée pour fournir un bruit faible. Le signal lumineux est amplifié par une unité d'amplification optique et est alimenté à une unité de retrait d'émission spontanée amplifiée. Le signal lumineux traverse l'unité d'émission spontanée amplifiée et il est réfléchi dans la direction orthogonale par rapport à la direction de la propagation de la lumière. Par conséquent, le système amplificateur optique se caractérise par un bruit faible.
