There are actually in essence two possible explanations for your productive refractive index variation on mild irradiation: heating on the LiNbO3:Fe substrates and, For that reason, from the LC during the microchannel, and director reorientation in the electrical subject induced by gentle during the LiNbO3:Fe substrates.
