ABSTRACT:
WDM optical signals are amplified using optical parametric amplification by applying an appropriate separation of those optical signals according to their carrier angular frequencies. These angular frequencies are within the two principal amplification bands defined by the non-linear optical medium used for optical parametric amplification. It is advantageously proposed to launch into the non-linear optical medium in one direction the optical signals of carrier frequencies within the one amplification band, and in the opposite counter-propagating direction the optical signals of carrier angular frequencies within the other amplification band. The required pump radiation is launched co-linearly with the respective optical signals to be amplified.
