Giantly enhanced cross-phase modulation with suppressed spectral broadening is predicted between optically induced dark-state polaritons whose propagation is strongly affected by photonic bandgaps of spatially periodic media with multilevel dopants. This mechanism is shown to be capable of fully entangling two single-photon pulses with high fidelity.
