The coexistence of synchronized and desynchronized phases, known as a chimera state, has attracted significant interest in the field of nonlinear dynamics. We have observed chimera states in photonic spiking neural networks based on networked degenerate optical parametric oscillators. We confirmed that the dynamics of chimera states have been changed depending on edge density of the network structures.
