Abstract :
The authors propose and demonstrate a technique for phase conjugation of lightwave signals with an efficiency that is independent of the signal polarisation. Using either optical fibre or a semiconductor optical amplifier as the nonlinear element, a signal-polarisation dependence of about +or-1dB in the conjugation efficiency was obtained.
