… 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 …

… This small pump ratio is close to the optimal one for the crystals with a large coupling constant.
The photorefractive crystals we used in our experiments are quite slow at low intensities. …

… photorefractive crystal (such as SPS: Sn2P2S6) could be employed to enhance the
sensitivity-bandwidth product of a LIGO type gravitational wave detector augmented by a White Light …

… demonstrate slow and fast light at room temperature by dispersive phase-coupling in a
photorefractive SBN:60 crystal… Compared to slow light based on CPO in ruby crystals [10], gain in …

… For this demonstration, we choose a room temperature solid-state material, namely, a
photorefractive crystal, wherein slow-light is produced by the narrow-band gain due to two-beam …

… In the demonstrations of slow light in photorefractive (PR) … Here we demonstrate that the
slowdown of light in a PR crystal … may indeed reduce the Sn2P2S6 crystal response time to a …

… /S is a property of the host photo refractive crystal and not subject to variation except by heating…
in the writing of a photorefractive grating is the response time. The photorefractive effect is …

… whose in tensity varies sinusoidally with posi tion in the crystal. If this sinusoidal pattern of
light forms within a photo refractive crystal, electric charges will move to generate an electric …

… 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 …

… The SPS photorefractive crystal has already been used for slow light in the visible … slow
and the fast light propagation scheme using the beam fanning in the SPS photorefractive crystal …
