Latest Patents

One of Michel Bégin's latest patents is the "Superfluorescent Fiber Source." This invention presents a low-cost superfluorescent fiber source that utilizes a gain medium in an optical fiber, pumped in counter-propagation by a pump source. This setup produces superfluorescent radiation, with a first coupler selectively transmitting the pump signal backward and the superfluorescence forward. A second coupler is positioned to manage the backward propagating superfluorescent radiation and the pump signal, ensuring that feedback to the pump laser is avoided. This source can be constructed using readily available optical components, making it easy to assemble without requiring precise alignment.

Another notable patent is the "Gain-Locked Dual Stage Optical Amplifier." This invention involves an optical waveguide, such as an optical fiber, equipped with at least two amplifying stages. Each stage is powered by a corresponding pump source, and mechanisms are in place to monitor and control the initial pump power of both sources. This ensures that the pump signals are set to a controlled value based on the unabsorbed signal from the first amplifying stage, enhancing the overall performance of the optical amplifier.
