Abstract (en)
[origin: WO0217453A1] The invention concerns a semiconductor optical amplifier comprising a buried active guide structure (12). The invention is characterised in that an external strain is applied to said active guide structure (12) such that it is subjected to a global strain which makes said amplifier insensitive to the polarisation of the light to be amplified, said external constraint resulting from a force induced by deposit of a material (50) against the stripe (15) enclosing said active guide structure (12).
