ABSTRACT:
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.
