Abstract
The invention relates to a semiconductor optical amplifier including a buried guide active structure (12), characterized in that the guide active structure (12) is subjected to an external stress to render the gain of said amplifier insensitive to the polarization of the light to be amplified, said external stress coming from a force induced by a deposit of a material (50) against a ridge (15) surrounding said guide active structure (12).
