20.500.12556/RUL-155352 Polarization patterning in ferroelectric nematic liquids via flexoelectric coupling The recently discovered ferroelectric nematic liquids incorporate to the functional combination of fluidity, processability and anisotropic optical properties of nematic liquids, an astonishing range of physical properties derived from the phase polarity. Among them, the remarkably large values of second order optical susceptibility encourage to exploit these new materials for non-linear photonic applications. Here we show that photopatterning of the alignment layer can be used to structure polarization patterns. To do so, we take advantage of the flexoelectric effect and design splay structures that geometrically define the polarization direction. We demonstrate the creation of periodic polarization structures and the possibility of guiding polarization by embedding splay structures in uniform backgrounds. The demonstrated capabilities of polarization patterning, open a promising new route for the design of ferroelectric nematic based photonic structures and their exploitation. liquid crystals nonlinear optics true false true Angleški jezik Ni določen Članek v reviji 2024-03-27 11:55:56 2024-03-27 11:55:57 2024-10-02 13:45:46 0000-00-00 00:00:00 2023 0 0 10 str. art. 3029 Vol. 14 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 537 2041-1723 10.1038/s41467-023-38749-2 154085635 s41467-023-38749-2.pdf s41467-023-38749-2.pdf 1 B4DC07D6F2082668077BA9FE6B4ECB2A 8758a98008365490b60a466eca5d870e98ff89ceee278970c5845e3792a8c10c 21f4f027-ec29-11ee-aa14-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182196 https://www.nature.com/articles/s41467-023-38749-2 0 09b1e689-ec29-11ee-aa14-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182195 Fakulteta za matematiko in fiziko 0 0 0
