… , slow light with traditional ferroelectric photorefractive crystals is useful first of all for the
modeling different wave-mixing … This is not, however, the only field for photorefractive lightpulse …

… Our photorefractive slow light system allows combining low group velocity with large …
photorefractive material at room temperature. We specifically address the question of the slow light …

… Recently it has been shown theoretically that the slowing down of the light pulses can be
achieved with photorefractive backward-wave four-wave mixing [18, 19]. If the nonlinear …

… In the demonstrations of slow light in photorefractive (PR) materials, the delays are only
reported for long pulse durations (ms to s) that are in discrepancy with typical ns-pulse length in …

… In this Letter, we demonstrate the possibility to all-optically control the group delay in a
photorefractive (PR) crystal by the use of the two-wave mixing (TWM) effect in the pulse regime at …

… , photorefractive and free-carrier gratings in semiconductors at high intensity excitation or
dynamic population gratings allow four-wave mixing based slow light with much shorter light …
