Patent

CA 2427434

According to the invention, the signal quality on passing through a device for the transmission of optical signals, comprising a waveguide with a doped region, containing a material suitable for the amplification of optical signals may be impaired as little as possible, whereby the doped region has a pre-defined absorption and may have the amplification thereof altered by the injection of pumping light.

La présente invention concerne un dispositif permettant de transmettre des signaux optiques. Ce dispositif comprend un guide d'ondes présentant une zone dopée pourvue d'un matériau adapté à l'amplification de signaux optiques. L'objectif de la présente invention est que la qualité du signal se dégrade le moins possible en traversant ce dispositif. A cette fin, la zone dopée présente un pouvoir d'absorption prédéfini et son amplification peut être modifiée par irradiation de lumière de pompage.
