Abstract
We study the consequences of the application of an electric field on t he non-linear transparency effects given by the light-induced creation of an isotropic droplet in a twisted nematic liquid crystal cell boun ded by two dichroic polarizers. The possibility of voltage control is shown. A simple mathematical model is presented for the description of the phenomenon. Experimental results are presented and discussed by c omparison with theoretical predictions.
