  • Optical transmission systems including optical amplifiers and methods
    Patent number: 7010229
    Abstract: Optical transmission systems of the present invention include at least one optical amplifier generally including an optical signal amplifying medium supplied with pump power in the form of optical energy in via an optical pump source. The pump source includes multiple optical sources, at least two of which provide optical energy in first and second wavelength ranges separated by a frequency difference. The amplifier includes a wavelength controller configured to adjust the wavelength range of at least one of the optical sources to vary the frequency difference in a manner sufficient to vary optical intensity noise produced when the optical energy from the multiple optical sources is combined.
    Type: Grant
    Filed: July 16, 2004
    Date of Patent: March 7, 2006
    Assignee: Corvis Corporation
    Inventors: David J. Copeland, John J. Veselka, Jr., Donald M. Cornwell, Jr., Thomas D. Stephens, Dean M. Smith, Mark A. Laliberte
