Latest Patents

Yves Rouleau holds a patent for a "Gain-locked dual stage optical amplifier." This invention involves a gain-locked dual stage or multi-stage optical amplifier. The input signal is injected into an optical waveguide, such as an optical fiber, which is equipped with at least a first and a second amplifying stage. Each amplifying stage is powered by a corresponding pump source that produces a pump signal with an initial pump power value. The invention includes mechanisms to monitor the initial pump power of both the first and second pump sources, as well as the pump power of the portion of the signal that remains unabsorbed by the first amplifying stage. The initial pump power of both pump signals is controlled together, set to a common controlled value calculated based on the pump power of the unabsorbed signal from the first amplifying stage.
