The Liquid Crystals and Photonics Group is part of the department of Electronics and Information Systems (ELIS) at the Faculty of Engineering of the Ghent University in Belgium. The research aims at the development of new electro-optical devices based on liquid crystals, electrophoretics, luminescent materials or solar cells and is headed by Prof. dr. ir. Kristiaan Neyts.
The Liquid Crystal research is related to displays, switchable interconnections and biosensors. We investigate liquid crystal based spatial light modulators, color filters, silicon waveguides and non-linear spatial solitions. The expertise is based on technology (clean-room facilities for photolithography and device assembly, including glass substrates and silicon wafers), experimental setups (electro-optical characterization, current measurements, polarization microscopy) and numerical simulations (LC director calculation, optical transmission, waveguiding).
Electrophoresis is used in paper-like displays and biosensing. We study the particle motion by opto-electronic measurements (microscopy, current), in particular in non-polar media. Different theoretical models have been developed for the transport and charging of particles and inverse micelles. Another paper-like technology that is being studied is electrochromism.
The outcoupling of light from organic LED's is studied experimentally and theoretically. There is optical modelling based on coherent emission and propagation in structured media and on ray tracing (ASAP). This research is linked to applications in displays, lighting and photovoltaics.
The group is involved in several European projects, bilateral projects with companies and scientific projects funded by government institutions and Ghent University. The group co-owns 5 patents and is co-author of over 200 scientific journal papers in the field.
Our webpage gives an overview of our research group. Information is provided about the members of our group, the ongoing research and collaborations with other research groups. Further it gives a list of our publications and the received awards. On our tutorial pages, an introduction is given into liquid crystals, OLED's, electrophoretic ink and electrochromic devices.
