You will find fundamentally two probable motives with the effective refractive index variation upon mild irradiation: heating from the LiNbO3:Fe substrates and, consequently, from the LC inside the microchannel, and director reorientation in the electric field induced by light inside the LiNbO3:Fe substrates. Worthy of note, the key pyroelectric result https://nathanielj524oih6.blogadvize.com/profile
