Abstract :
In this paper, we report our most recent results about the huge optical nonlinearity of methyl red (MR)-doped 5CB thin cells. The basic concepts of the surface-induced nonlinear effect interpretation are recalled and possible methods to obtain a better control of the samples response are discussed.
