ABSTRACT:
A non-resonating laser diode optical amplifier comprises a strip of optically active material forming an amplifying optical guide, covered with a confinement sheath and defined by antireflection coating layers. The strip has end portions whose thickness is lesser than that of a central portion and is selected to give a low value to the difference between the wavelengths corresponding to the reflectivity minima for the two inherent polarization states. The end portions are connected to the central portion by transition sections having a progressively increasing thickness.
