Photo-alignment of liquid crystals in micro capillaries with point-by-point irradiation

A. Siarkowska / M. Jóźwik / S. Ertman / T. Woliński / V. Chigrinov
Published Online: 2014-06-29 | DOI: https://doi.org/10.2478/s11772-014-0188-9


A photo-alignment method for micro capillaries based on the SD-1 azo-dye is demonstrated. In this work a liquid-crystal molecules aligning layer is created by point-by-point irradiation of the azo-dye film by using an UV laser light. The method opens up new possibilities for an improved molecules’ orientation control in both glass- and polymer-based photonic liquid crystal fibres.
