Abstract
In this paper the neuron operation using stimulated Brillouin scattering (SBS) in optical fiber is described. The inherent optical feedback by the backscattered Stokes wave in optical fiber leads to instabilities in the form of optical chaos. At low power, the nature of the Brillouin instability can occur below threshold. At high power, the temporal evolution above SBS threshold is periodic and can become chaotic. Control of chaos induced transient instability in Brillouin-active fiber is experimentally implemented with Kerr nonlinearity having a non-instantaneous response in netowork systems. Controlling chaotic instabilities can lead to multistable periodic states; create optical logic ’on’ or high level ”1” or ’off, or low level ”0”. It can be used in neural networks. It can also lead, in principle, to large memory capacity.
