Bistability and dual-frequency nematic liquid crystals

Palto S. P., Barnik M. I.

Opto-Electronics Review

2007

Vol. 15, No. 1

52-59

Different modes of bistable switching in liquid crystals with frequency inversion of the dielectric anisotropy sign are discussed. The study is performed by numerical simulation and experimentally. It is shown that dual frequency driving can be effectively used to control switching between topologically equivalent and non-equivalent director field distributions. The experimental results on temperature performance of the dual-frequency switching and possible driving methods for energy consumption and expanding the temperature range are presented.

General properties of lasing effect in chiral liquid crystals

Palto S. P., Shtykov N. M., Umansky B. A., Barnik M. I., Blinov L. M.

Opto-Electronics Review

2006

Vol. 14, No. 4

323-328

Numerical simulations and experimental studies of the lasing effect in chiral liquid crystals are presented. It is shown that ring-like light emission, which is often observed experimentally, is a true lasing effect. Lasing condition and different modes in thin liquid crystal layers are discussed.
