Orientational photorefractivity was observed in ferroelectric liquid crystal (FLC) composites containing oxidized and reduced chromophores. The orientational response was a result of the space-charge field coupling to the bulk polarization of the FLC and not to dielectric anisotropy as with nematic liquid crystals. Results showed that the photorefractive electro-optic mechanism was derived from orientational effects. To increase the likelihood of observing the linear electronic electro-optic effect and orientational contributions, one possibility is to use homeotropically aligned FLCs with a transverse applied field.
