Light-induced pitch transitions in photosensitive cholesteric liquid crystals: Effects of anchoring energy

Tetiana N. Orlova, Roman I. Iegorov, Alexei D. Kiselev

We experimentally study how the cholesteric pitch, $P$, depends on the equilibrium one, $P_0$, in planar liquid crystal (LC) cells with both strong and semistrong anchoring conditi…
