CA 2070194

A polarisation-independent amplification device comprising an optical semiconductor amplifier. The amplification device input signal is fed to one side of the amplifier and a reflector is provided at the other side. The amplification device output signal, formed by the amplification device input signal reflected by the reflector and amplified by the ampl- ifier, is taken off at the first side of the amplifier. The reflector is reciprocal, a signal or signal component fed thereto and having a polarisation perpendicular to the principal axis of the amplifier being reflected as a reflection signal having a polarisation which is virtually parallel to said principal axis and vice versa.
