Nanosecond electro-optic switching of a liquid crystal

Electrically induced reorientation of nematic liquid crystal
(NLC) molecules caused by dielectric anisotropy of the
material is a fundamental phenomenon widely used in modern
technologies. Its Achilles heel is a slow (millisecond)
relaxation from the field-on to the field-off state. We
present an electro-optic effect in an NLC with a response time
of about 30 ns to both the field-on and field-off switching.
This effect is caused by the electric field induced
modification of the order parameters (EMOP) and does not
require reorientation of the optic axis (director).
