You'll find generally two doable good reasons for that successful refractive index variation on gentle irradiation: heating with the LiNbO3:Fe substrates and, For that reason, in the LC within the microchannel, and director reorientation in the electrical field induced by light within the LiNbO3:Fe substrates.
