The two-stage switch-on dynamics of a nematic pi-cell are explored in detail using a convergent beam fully-leaky guided mode technique. The cell shows an initial switch-on with a time scale in the range several ms to tens of ms (depending on drive voltage) from the symmetrical H state to a new and semistable H state. It then slowly changes (over several hundred ms) to the final stable asymmetrical H state.

    Two electro-optical phenomena of liquid-crystal blue phase with cubic lattice structure-(1) a fast and reversible shift in reflection band and (2) a phase transition from blue phase to chiral nematic phase-are observed in this study. By increasing the magnitude of a vertical electric field, the...
