Analysis of second-order electro-optical effect in the vicinity of the phase transition temperature

Abstract

Liquid crystals have been known to show the second-order electro-optical effect(Kerr effect), which caused by the electronic polarization and the orientational polarization simultaneously. Because of the high speed response, the main contribution of the second-order electro-optical effect has been believed to be an electronic polarization In this report, we studied the second-order electro-optical effect in the dye-doped liquid crystals, and we found that the main contribution of the second-order electro-optical effect was the orientational polarization.
