Zenithal Bistable display devices have been made which are compatible in size and functionality with current mobile phone or pager displays. Radical improvements in the viewing characteristics particularly in reflective mode are shown. Furthermore th

Previous work has shown that when short-pitch cholesteric liquid crystals are aligned in cells with the helical axis in the plane of the substrate in a well-defined direction, then application of an electric field across the cells may result in micro

We report an examination of the cloth-rubbing process, widely used to effect liquid crystal alignment, from a simplified microscopic perspective. We define strength of rubbing by the average applied force per rubbing fibre (approximately 11-22μN und

Liquid crystal(LC)surface alignment, which controls off‐state contrast in LC displays, is commonly achieved by directional rubbing of polyimide‐coated substrates. In order to better understand the alignment mechanism we have used tapping‐mode a

A waveguide consisting of a thin (< 1 μm) layer of nematic liquid crystal sandwiched between two parallel aligned gratings is described. Grating coupling to guided modes is demonstrated by monitoring the reflection and transmission from the cell as

The optical properties of grating coupled waveguides are theoretically modeled and practically demonstrated using nematic and smectic liquid crystals as thin (0.7 μm) waveguide layers. Voltage induced reorientation of the liquid crystal is shown to

Periodically corrugated waveguides consisting of a ZnS layer clad on one side by Al have been made free standing by deposition on to photoresist followed by removal of the photoresist using a solvent. Coupling of laser light into guided modes causes

Atomic force microscopy (AFM) has been used to modify a polyimide surface to give controlled liquid crystal (LC) alignment, and to examine the modification produced. Strong LC azimuthal anchoring was observed typically for normal forces >300 nN and l
