20.500.12556/RUL-167047 Liquid crystal 3D optical waveguides based on photoalignment 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 waveguides are terminated with +1 or −1 surface defects through which the light incouples/outcouples. The effect of the straight waveguide thickness and the radius of curvature of the curved waveguides on the attenuation of the light in the waveguide is experimentally explored. The experiments are supported with numerical simulations of light propagation through both types of waveguides and outcoupling out of the straight waveguides. Furthermore, the effect of the size of the −1 defect terminations on the outcoupling efficiency is explored using simulations. Based on the presented design and manufacturing approach, liquid crystal optical waveguides of various shapes can be realized accurately with low-cost. soft matter physics liquid crystals photonics photopatterning optical waveguides fizika mehke snovi tekoči kristali fotonika fotostrukturiranje optični valovodi true false true Angleški jezik Slovenski jezik Članek v reviji 2025-02-05 13:00:47 2025-02-05 13:00:48 2025-02-06 03:51:29 0000-00-00 00:00:00 2025 0 0 8 str. iss. 4, art. no. 2402174 Vol. 13 Feb. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 535:538.9 2195-1071 10.1002/adom.202402174 214225411 Advanced_Optical_Materials_-_2024_-_Ropac_-_Liquid_Crystal_3D_Optical_Waveguides_Based_on_Photoalignment.pdf Advanced_Optical_Materials_-_2024_-_Ropac_-_Liquid_Crystal_3D_Optical_Waveguides_Based_on_Photoalignment.pdf 1 66E586DFF449FD8FFFC33247F98038D6 002711b49150d5395864bb0e5d9c20f1a6b4b219215c24d2b4c781be7c5d104e 6b0ce052-e3b8-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199186 https://onlinelibrary.wiley.com/doi/10.1002/adom.202402174 0 71f80e34-e3b8-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199187 Fakulteta za matematiko in fiziko 0 0 0
