Abstract. The possibility of storing information in an amplifying optical fibre loop operating in a laser regime is discussed. Numerical simulations show that storage is possible and optimal when data are encoded in one of the polarization eigenstates of the fibre, provided the polarization direction of the light propagating inside the loop is switched between two orthogonal states every round trip.
