Surface stabilized topological solitons in nematic liquid crystals
Inge Nys, Brecht Berteloot, Guilhem Poy
Izvirni znanstveni članek
Oznake: nematski tekoči kristali;topološki solitoni;optika;nematic liquid crystals;topological solitons;optics;
Photo-alignment is a versatile tool to pattern the alignment at the confining substrates in a liquid crystal (LC) cell. Arbitrary alignment patterns can be created by using projection with a spatial light modulator (SLM) for the illumination. We demonstrate that a careful design of the alignment pat ...

Ring-shaped liquid crystal structures through patterned planar photo-alignment
Brecht Berteloot, Inge Nys, Guilhem Poy, Jeroen Beeckman, Kristiaan Neyts
Izvirni znanstveni članek
Oznake: fizika mehke snovi;tekoči kristali;soft matter physics;liquid crystals;
Patterned liquid crystal (LC) configurations find widespread applications in functional devices such as lenses, gratings, displays and soft-robots. In combination with external stimuli such as an applied electric field, photo-alignment at the surfaces offers an attractive way to stabilize different ...

Liquid crystal 3D optical waveguides based on photoalignment
Peter Ropač, Yu-Tung Hsiao, Brecht Berteloot, Yera Ussembayev, Inge Nys, Miha Ravnik, Kristiaan Neyts
Izvirni znanstveni članek
Oznake: fizika mehke snovi;tekoči kristali;fotonika;fotostrukturiranje;optični valovodi;soft matter physics;liquid crystals;photonics;photopatterning;optical waveguides;
A novel design and approach for the realization of liquid crystal optical waveguides using photopatterning as a manufacturing method is presented. The developed method is used to demonstrate straight waveguides of different widths and curved waveguides with different radius of curvature. The wavegui ...
