20.500.12556/RUL-182378 Slow light by dual-periodic self-similar dielectric multilayered films We demonstrate the emergence of slow-light in dual-periodic dielectric one-dimensional photonic crystals with self-similar features at different length scales. Specifically, using numerical modelling, we explore self-similar photonic crystals which are formed as effective combinations of dual periodic stacks of dielectric layers and show that the emergent photonic band diagram can be widely designed by different structural parameters. The width and the position of bandgaps can be designed to work over a wide range of bands and frequencies. The proposed design also leads to the emergence of flat bands and major slow-light regimes, with possible group refractive index of light as large as 103 and in a range of bands. optics photonics photonic crystals self-similarity optika fotonika fotonski kristali samopodobnost true false true Angleški jezik Slovenski jezik Članek v reviji 2026-05-08 13:16:26 2026-05-08 13:16:26 2026-05-10 04:14:33 0000-00-00 00:00:00 2023 0 0 Str. 22385-22395 no. 14 Vol. 31 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 535:538.9 1094-4087 10.1364/OE.493703 156570371 oe-31-14-22385.pdf oe-31-14-22385.pdf 1 5076384A6A0F2DA33349DBFB7E715A1E 51a2a0d0f396020ad96327bfeeee1cc30ba76795d3afe0b240aa6890dd42773d 584f13d8-4acf-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=233572 https://opg.optica.org/oe/fulltext.cfm?uri=oe-31-14-22385 0 64dcdd7d-4acf-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=233573 Fakulteta za matematiko in fiziko 0 0 0
