We have realized a photonic spiking neuron that can simulate two types of spiking modes, defined as Class-I and Class-II, using two degenerate optical parametric oscillators with an antisymmetric coupling. In this presentation, we report the experimental results of combinatorial optimization for a graph problem with 2000 nodes using the spiking dynamics of the photonic spiking neurons.
