However, the fabrication imperfections at the nanoscale inevitably introduce disorder that affects or even destroys many functionalities of subwavelength photonic devices. Here we suggest a novel concept to achieve a robust bandgap which can endure disorder beyond 30% as a result of the transition from photonic crystals to Mie-resonant metamaterials. We demonstrate photonic waveguides and cavities with strong robustness to position disorder. Utilizing Mie-resonant metamaterials with high refractive index provides an alternative approach to the bandgap-based nanophotonic devices instead of harnessing the fabrication precision, and also brings new functionalities.The work has partially been supported by the ERC Consolidator Grant (TOPOLOGICAL), the Royal Society, Wolfson Foundation, the Ministry of Education and Science of the Russian Federation (3.1500.2017/4.6), the Russian Foundation for Basic Research (18-02-00427), the Australian Research Council, and the European Union Horizon 2020 research innovation programme under the Marie SkłodowskaCurie Grant (No. 752102).application/pdfen-AU© 2019 The Authors.
