We propose and theoretically investigate an all-dielectric bowtie whisperinggallery-mode (WGM) resonator which consists of two tip-to-tip coupled semiconductor nanorings with triangular cross section separated by low refractive index material gap. Mode splitting of symmetric WGM and antisymmetric WGM is observed and analyzed. Due to extremely field enhancements by the “slot&#x2... https://foldlyers.shop/product-category/fridge-or-freezer/
