In this work, we demonstrate polarization-independent four-wave mixing using a single semiconductor optical amplifier. The result is obtained using a polarization-diversity scheme, in which all the injected fields are split by a polarization beam splitter and the two resulting patterns are injected counterpropagating in the amplifier. The use of two orthogonally polarized pumps allows a conjugate generation with efficiency also independent of the signal-conjugate detuning. A comparison of the amplifier performance with mono- and bidirectional propagation is given.

Abstract
In this work, we demonstrate polarization-independent four-wave mixing using a single semiconductor optical amplifier. The result is obtained using a polarization-diversity scheme, in which all the injected fields are split by a polarization beam splitter and the two resulting patterns are injected counterpropagating in the amplifier. The use of two orthogonally polarized pumps allows a conjugate generation with efficiency also independent of the signal-conjugate detuning. A comparison of the amplifier performance with mono- and bidirectional propagation is given.File in questo prodotto:
