SECONDMENTS

The objectives of the mobility is to pursue the work started at ISM during my PhD. The general project is the design of hybrid glass/liquid-crystal optical systems. These systems are made by functionalization of ionic glass surfaces, via thermal poling, which are then used to produce µ-meter thick multi-domain liquid-crystals cells. It is of importance then to study the influence of such electrically treated glass surface on liquid-crystals alignments.

After exploring several possibilities of liquid-crystals orientations, via poled µ-structured glass, following work will investigate the durability of the treatment, the reorientation mode of the liquid crystal, the glass anchoring energy…

Also, the combination of PGLC (poled glass liquid-crystals) cell with ITO layers, in order to study the dynamic properties of LCs in contact with poled glass, needs to be conducted, and opens the possibilities to make novel light manipulation. This might initiate the conception and production of an hybrid electronic device using poled glass technology, in combination with liquid crystals, and ITO electrodes.

All the tasks listed above can be done at COPL, Pr Galstian’s team being specialized in such characterizations and liquid-crystals devices production.

• Poled glass liquid crystal cell characterization
• Poled glass ionic structure analysis with EDS
• Cell and electrode design for future applications (optical switches, displays)
• Conception and production of an hybrid optical device
