Strong Mode Coupling and High-Q Supercavity Modes in Subwavelength Dielectric Resonators

Koshelev, Kirill; Bogdanov, A. A.; Gladyshev, Sergey; Sadrieva, Zarina; Rybin, Mikhail; Samusev, Kirill; Limonov, Mikhail F.; Kivshar, Yuri


We reveal that isolated subwavelength dielectric resonators support states with giant Q-factors similar to bound states in the continuum formed via destructive interference between strongly coupled eigenmodes and characterized by singularities of the Fano parameters.
