There are actually mainly two probable motives to the powerful refractive index variation on light-weight irradiation: heating with the LiNbO3:Fe substrates and, For that reason, in the LC from the microchannel, and director reorientation in the electric field induced by light-weight in the LiNbO3:Fe substrates.
