“…projection displays [2] and wavelength selective filters in ROADMS for telecommunication respectively. For the latter, such defect formation in planar aligned LCOS devices is particularly important [3]. For example, the "ROSES" demonstrator is based on a LCOS spatial light modulator proposed by Crossland et al [4].…”

“…Bechtold and Oliveira [22] experimentally investigated the equilibrium configuration of the director for a submicron patterned substrate, creating alternating homeotropic and random planar stripes by selectively irradiating a SAM with deep UV. James et al [23,24] also studied striped patterns in their modelling of an LCOS (Liquid Crystal on Silicon) device, where the patterning was achieved using highresolution linear electrodes with rewritable input voltages.…”

Patterned Self-Assembled Monolayers (SAMs) promoting both homeotropic and planar degenerate alignment of 6CB and 9CB in their nematic phase, were created using microcontact printing of functionalised organothiols on gold films. The effects of a range of different pattern geometries and sizes were investigated, including stripes, circles and checkerboards. Evanescent Wave Ellipsometry was used to study the orientation of the liquid crystal (LC) on these patterned surfaces during the isotropic-nematic phase transition. Pretransitional growth of a homeotropic layer was observed on 1 µm homeotropic aligning stripes, followed by a homeotropic mono-domain state prior to the bulk phase transition. Accompanying Monte-Carlo simulations of LCs aligned on nano-patterned surfaces were also performed. These simulations also showed the presence of the homeotropic mono-domain state prior to the transition. * Electronic address: s.d.evans@leeds.ac.uk

Fourier transform spectroscopy (FTS) is a fundamental analytical tool utilized in many chemical and biological analysis applications. It is especially well-known and widely used for its powerful analytical techniques to measure the spectra of a weakly extended source. The purpose of this study is to create a compact, low-cost FTS system utilizing a miniature liquid crystal interferometer. This design is unique because the optical path difference (or phase difference) is controlled by the applied voltage. The optical path difference is further improved by incorporating two reflective mirrors between the two polarizers. In this article, we will present the theoretical model, numerical simulation, and experimental results of the proposed FTS. Based on the experimental results, the FTS performs in accordance with the theoretical predictions, achieves a maximum optical path difference of 210 m, and a resolution of 1nm at a wavelength of 630 nm. The instrumental response refresh rate is just under 1 second. Absorbance measurements were conducted for single and mixed solutions of deionized water and isopropyl alcohol, successfully demonstrating agreement with a commercial system and literature values.
