Nonequilibrium photonic transport and phase transition in an array of optical cavities

Understand

We characterize photonic transport in a boundary driven array of nonlinear optical cavities.

• We find that the output field suddenly drops when the chain length is increased beyond a threshold.
• After this threshold a highly chaotic and unstable regime emerges, which marks the onset of a super-diffusive photonic transport.
• We show the scaling of the threshold with pump intensity and nonlinearity.
