You will find mainly two achievable explanations to the effective refractive index variation upon light irradiation: heating of your LiNbO3:Fe substrates and, Therefore, of the LC within the microchannel, and director reorientation in the electric subject induced by light-weight inside the LiNbO3:Fe substrates.
