摘要
We propose a radiation-free dielectric nanocavity with all-evanescent confinement based on perfect mode-matching and minimal use of negative permittivity. A record-low mode volume within high-index core material, supporting high-Q(Q/V), may enable efficient active nanophotonic components. (C) 2018 Optical Society of America
