Abstract
It is reported here that it was observed that in suitable nematic liquid crystals in very thin sandwich cells from the threshold of domain formation up to the highest practicable field strength, the inverse domain width is proportional to the applied dc electric field, while dynamic scattering does not occur. Since such a cell performs as an electrically controllable optical grating which can be made to have very high diffraction efficiency, this effect may also be of practical interest.
