Abstract

Electro-optical effects in room temperature blue phases (BP) with positive dielectric anisotropy have been studied. It is shown that the maximum wavelength of the Bragg reflection of blue phases, BP II and BP I, shifts to longer wavelength with increasing electric field. The electric field influences more strongly on BP II: a reversible shift of (lambda) ₀ up to 80 nm was observed.
