Abstract
The invention relates to an optical amplifier device including a semiconductor optical amplifier component () including a guide active structure (), characterized in that the guide active structure () is subjected to a stress external to said component () coming from integrating said component () in said device, and in that said component () has a controlled sensitivity to the state of polarization of the light to be amplified in order to render the gain of said optical amplifier device insensitive to the polarization of said light to be amplified.
