  • Optical fibre amplifiers
    Patent number: 6650400
    Abstract: An optical amplification system has an active fibre section having an optical fibre 10 and containment means 8, 12 containing light of a specific wavelength within the active fibre section. The specific wavelength of light is the result of the spontaneous transition of photons. The contained photons stimulate further photons emissions, which depopulates energy levels involved in the amplification process.
    Type: Grant
    Filed: June 13, 2001
    Date of Patent: November 18, 2003
    Assignee: Nortel Networks Limited
    Inventors: Andrew V Maroney, Daria Crippa, Jowan Masum-Thomas
