    Abstract: An optical signal amplifier includes a first semiconductor optical amplifier having an input for receiving an optical signal, and an output, wherein the optical signal is amplified by the first semiconductor optical amplifier resulting in an amplified optical signal. The optical amplifier also includes an optical signal isolator having an input in optical communication with the output of the first semiconductor optical amplifier, and an output, wherein the optical signal isolator receives the amplified signal from the first semiconductor optical amplifier and allows for transmission of an optical signal in a single direction. The optical amplifier further includes a second semiconductor optical amplifier having an input for receiving the amplified optical signal from the optical signal isolator, and an output, wherein the amplified optical signal is amplified by the second semiconductor optical amplifier resulting in a twice amplified optical signal.

    Abstract: An optical amplifier comprises a trivalent thulium-doped optical fiber; a first pump light emitting device optically coupled to the fiber for generating a primary pump source at a first wavelength, and a second pump light emitting device optically coupled to the fiber for generating a secondary pump source at a second wavelength. In a preferred aspect of the present invention, the amplifier also includes a third (auxiliary) pump light emitting device optically coupled to the fiber for generating a third pump source at a third wavelength. Each of the amplification signals comprise at least one pre-selected wavelength. The first amplification signal has a wavelength pre-selected to provide a reduced noise figure for the amplifier. The second amplification signal has a wavelength pre-selected to increase the optical efficiency of the amplifier. The third amplification signal can have a wavelength pre-selected to populate the 3F4 energy level of the fiber, and to minimize depletion of the 3H6 ground state.

    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.
