All-optical Leaky-Integrate-and-Fire Neuron Based Cascaded Microrings with Power-tunable Auxiliary Light

We demonstrated an all-optical Leaky-Integrate-and-Fire neuron based cascaded microrings with power-tunable auxiliary light. The compact LIF neuron enables flexibly realizing synaptic weighting operation due to synaptic plasticity of a single microring, and generating layer-individual spikes.
