G. Nekrasov et al., MODULATION OF THE ENERGY COEFFICIENT OF REFLECTION FROM GLASS-FERROELECTRIC SMECTIC-C-ASTERISK INTERFACE IN ELECTRIC-FIELD, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 263, 1995, pp. 285-291
Peculiarities have been studied of modulation of nonpolarized light in
glass-plane parallel ferroelectric smectic C boundary in the vicinit
y of total-internal-reflection angle under the action of electric fiel
d. LC materials with optical inclination angle of the local director o
f the smectic layer with respect to normal to the layer 45 degrees are
discussed. Optical characteristics are studied of modulated light bea
m for the cases of one- end two-fold reflection from the boundary. The
results of investigations makes it possible to contruct an LC-valve c
haracterized byhigh transmission (approximate to 90%) of nonpolarized
light in a wide spectrum range in the open state.
