FERRO ELECTRIC CRYSTAL OPTICAL DEVICE AND MAKING THEREOF

摘要

Excellent ordering in ferroelectric liquid crystal optical devices is obtained by utilizing a material having a smectic C phase and no higher temperature orthogonal smectic phases. Ordering is accomplished by the combination of 1) contacting the liquid crystal material in the smectic C phase with an ordering substance and 2) subjecting the liquid crystal material to a slowly varying electric field.
