“…The second approach is more promising, but photo-aligned layers are normally not reversible. Two recent papers [39,40] study nematic LCs with H-bonded dye-polymer complex, which seem to be promising materials to significantly alter the local properties of LCs using light tuning. Materials like these may lead to direct light modulation of the cell refractive index and allow full exploitation of the enormous beam-coupling potential of LC cells.…”

We explore the transfer of an incident light pattern onto the liquid crystal (LC) bulk in a photorefractive cell through an integrated photoconducting layer that modulates the electric field applied to the device. The electrical properties and the strength of modulation are investigated as a function of the incident light intensity as well as the frequency and amplitude of the applied voltage, for two LCs with very different electrical conductivity. A simplified electrical model of the cell is proposed, demonstrating that the LC conductivity is a key factor determining the beam-coupling strength.
