| contents | We demonstrate the perfect superconducting diode effect (SDE) -- unidirectional supercurrent with 100% diode efficiency -- in light-driven nonequilibrium systems. Although the perfect SDE is difficult to achieve in equilibrium, monochromatic light induces the perfect SDE in systems lacking inversion and time-reversal symmetries. More strikingly, multi-frequency light enables the perfect SDE even in centrosymmetric systems via dynamical symmetry breaking. Our results establish a general principle for realizing unidirectional superconducting transport based on nonequilibrium control and symmetry engineering. |
