Abstract
The assembly is implemented in the form of an optical head integrating not only an optical isolator (6, 8), but also a semiconductor amplifier and phase modulator (18). The amplifier-modulator is aligned parallel to the light-emitting laser (2) by a rotation compensator (14, 15) that compensates for the rotation applied by the isolator to the polarization of light from the laser. The invention is particularly applicable to optical fiber telecommunications.
