In this paper we review the state of the art in the field of liquid-crystal tunable guided-wave
photonic devices, a unique type of fill-once, molecular-level actuated, optofluidic systems …

Liquid-crystal devices are a promising cheap alternative for terahertz light modulation, albeit
they suffer from problems associated with thick cells. Here we describe a few-micron-thick …

We numerically study structural transitions inside shallow sub-micrometre scale wells with
square cross section, filled with nematic liquid crystal material. We model the wells within the …

A planar bistable liquid crystal device, reported in Tsakonas et al.[Appl. Phys. Lett. 90,
111913 (2007) APPLAB 0003-6951 10.1063/1.2713140], is modeled within the Landau-de …

The switching properties of nematic liquid crystals under electrical and mechanical stresses
play a fundamental role in the design and fabrication of electro-optical devices. Depending …

Using an atomic force microscopy, we have measured the separation dependence of the
force between an atomically flat mica sheet and a micrometer-sized glass sphere immersed …

By use of the Landau–de Gennes phenomenological theory, we study the texture of a
nematic liquid crystal confined within a hybrid cell. Precisely, we consider cylindrically …

Polymer films nanoimprinted with checkerboard patterns of square wells align calamitic
(rodlike) liquid crystals vertically, horizontally, or tilted depending on the depth/width ratio of …

The paper is concerned with various issues surrounding the mathematical description of
defects in models of liquid crystals, drawing on experience from solid mechanics. The roles …

Diseases that affect the cornea can lead to severe vision loss and have tremendous social
impact. These diseases are associated to deviations from normal structural order and …
