ABSTRACT
The intricate polarization properties of Doppler-enhanced self-diffraction in linearly birefringent and optically active materials, such as bismuth silicon oxide crystals, are utilized to achieve real-time photorefractive spatial light modulation with contrast selection capability. The contrast reversal is explained in terms of the spatial modulation of the birefringence caused by an incoherent erasure beam.

    The transient diffraction response of a low-temperature-grown (LTG) photorefractive multiple quantum well (MQW) spatial light modulator (SLM) is studied experimentally as a function of the frequency and the on/off ratio of a single-sided applied voltage when a grating is written using a...

    We show that stimulated two-wave mixing is the origin of phase conjugate fields in self-pumped photorefractive mirrors. We predict that the bulk photovoltaic effect gives rise to an intensity-dependent frequency shift in the phase conjugate field and is the physical origin for the occurrence of...
