Abstract
An optical radiation amplifier, including an input port which receives the optical radiation and a first semiconductor optical amplifier (SOA), which is coupled to receive the optical radiation from the input port and is adapted to amplify the optical radiation to produce amplified optical radiation in response to a first current injected into the first SOA. The amplifier also includes an electro-absorption modulator (EAM), which is coupled to receive the amplified optical radiation and is adapted to modulate the amplified optical radiation in response to a modulation voltage applied to the EAM so as to produce modulated radiation. There is a second SOA, which is coupled to receive the modulated radiation and is adapted to amplify the modulated radiation in response to a second current injected into the second SOA.
