  • Optical amplifier and method
    Patent number: 6731423
    Abstract: A broad bandwidth optical amplifier (50) includes an optical pump source (52). A Raman chamber (56) is coupled to an output (54) of the optical pump source (52). An optical fiber ring (62) having a first end (64) is coupled to a first end (66) of the Raman chamber (56). A second end (60) of the optical fiber is coupled to a second end (58) of the Raman chamber (56). A doped optical fiber is coupled to a second end of the optical fiber ring. The Raman chamber produces a number resonant Raman stokes lines.
