Ferro-electric liquid crystal for fast switching optical components Ghent University
Ferro-electric liquid crystals (LCs) have an intrinsic permanent polarization and switch much faster than the well-known nematic LC. Recently the nematic ferro-electric LC phase (NFLC) has been discovered, which can be used in new display and photonic applications. The existing smectic ferro-electric LC phase will be combined with patterned photoalignment to realize periodic structures with arbitrary tilt of the helical axis. These components ...
