Jeong, Peter A.; Goldflam, Michael G.; Briscoe, Jayson B.; Vabishchevich, Polina V.; Nogan, John N.; Luk, Ting S.; Brener, Igal B.

Toroidal dielectric metasurface with a Q-factor of 728 in 1500 nm wavelength are reported. The resonance couples strongly to the environment, as demonstrated with a refractometric sensing experiment.
