Patents by Inventor Donald M. Cornwell, Jr.

Donald M. Cornwell, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Optical transmission systems including optical amplifiers, apparatuses and methods
    Patent number: 7133193
    Abstract: Optical systems of the present invention include amplifiers configured to achieve maximum signal channel in a span downstream of the transmitter and amplifier site and to decrease the interaction between the wavelengths at high signal channel powers. In addition, the system can include various types of optical fiber positioned in the network to provide for increased signal channel powers and higher gain efficiencies in the system.
    Type: Grant

  • 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.

  • Optical systems and methods and optical amplifiers for use therein
    Patent number: 6704139
    Abstract: Optical transmission systems of the present invention include at least one optical amplifier in which pump power being provided to an amplifying medium is amplified using a pump amplifier prior to being introduced into the amplifying medium. In various embodiments, a cascaded Raman resonator is used as a pump booster source to provide Raman amplification of the pump power being supplied from one or more pump sources to the signal channel amplifying medium.
