Abstract :
The sensitivity of optical amplifiers to signal polarisation is avoided with use of configurations in which two amplifiers are combined. We describe experiments with a series and a parallel arrangement of two optical amplifiers. The experiments demonstrate a polarisation-insensitive amplification for both configurations over a spectral range of at least 80 GHz.
