Abstract
The transmission intensity of liquid crystal 90° twisted structures with
asymmetric boundary conditions has been estimated. Such structures are relevant
for optoelectronic systems. The pretilt angle of nematic mesogen on every cell
substrate varied from 0 to 90°. Configurations of twist-cells were proposed for
application in infrared or terahertz range light modulators as well as in optically
rewritable electronic paper. It was shown that the increase of the pretilt angle
value results in rising of liquid crystal layer thickness from 6 to 33 μm
corresponding two first Gooch–Tarry minima.
