There are mainly two achievable good reasons with the productive refractive index variation on light irradiation: heating of your LiNbO3:Fe substrates and, Therefore, with the LC from the microchannel, and director reorientation in the electric field induced by mild while in the LiNbO3:Fe substrates. Meanwhile, to make certain ongoing aid, https://finnardpa.dm-blog.com/32519047/getting-my-lithium-niobate-crystal-to-work
