"lithographically-defined asymmetric and symmetric Mie-scatterers enables subwavelength control of wave transmission and reflections without deflecting to additional radiation channels... enables pre-defined chiral light propagation and backscattering-free resonances needed for frequency combs, solitons, sensing, and other nonlinear optical processes such as photon blockade, and regenerative oscillators... enhanced empirical quality factor extracted from the transmission spectra is demonstrated for the first time"
