Abstract
We study numerically the dynamics of a system composed of two artificial neurons connected via an erbium-doped fiber laser. In our system, the laser acts as an optical synapse whose dynamics is controlled with a signal generated by a presynaptic Hindmarsh–Rose neuron, while the laser output drives a postsynaptic Hindmarsh–Rose neuron. Depending on the laser parameter, the postsynaptic neuron can be turned to different dynamical regimes including silence, tonic spikes, bursts with different number of spikes, and chaos.
