Fig. 4: Self-pulsation behavior from a constant inputs.
From: Design of a monolithic silicon-on-insulator resonator spiking neuron
The red input pulses are effectively DC with respect to the resonator circuit, but occur over a short enough period of time to be considered AC for the biasing circuit. The blue trace shows the output of the neuron, and the yellow trace indicates the feedback signal that comes from the microring DROP port. The dashed box zooms in to show the shape of the spikes exiting the neuron and entering the feedback diode from the drop port during self-pulsation.
