  • Optical amplifier having automatic gain control using the amplified spontaneous emission as the monitoring parameter
    Patent number: 7019894
    Abstract: A method and apparatus for automatically controlling the gain of an optical amplifier. The method begins by establishing a setpoint for ASE power within a given wavelength range generated by the optical amplifier. The pump power supplied to the optical amplifier is adjusted to maintain the ASE power at the established setpoint. The setpoint for the ASE power is adjusted based at least in part on changes in signal input power.
