A single-polarization fiber optical amplifier and corresponding method is provided capable of amplifying an optical input signal by a fiber optic amplifier constructed of fiber which may be non-polarization-maintaining. The single-polarization fiber optical amplifier provides a direction-selective coupler...http://www.google.fr/patents/US5303314?utm_source=gb-gplus-shareBrevet US5303314 - Method and apparatus for polarization-maintaining fiber optical amplification with orthogonal polarization output
