Collective Coherence Resonance in Networks of Optical Neurons.

The stability of these dynamical patterns has been systematically investigated in dependence on the injection strength and detuning between the lasers. Mathematical modelling reveals: Quantum-dot lasers behave like optical neurons and show coherence resonance. - A collaboration between TU Berlin and University College Cork analyzed the influence of optical injection and feedback with delay in a microscopically motivated quantum-dot model.
