Abstract
An optical signal amplifier includes a Raman fiber amplifier and a semiconductor optical amplifier. The Raman fiber amplifier utilizes a portion of the pump radiation to amplify the optical signal resulting in an amplified optical signal and a residual pump radiation. The semiconductor optical amplifier receives the amplified signal and the residual pump radiation and utilizes the residual pump radiation to increase a saturation output power of the semiconductor optical amplifier while amplifying the amplified signal resulting in a twice amplified signal.
