Light scattered by subwavelength dielectric nanoantennas can be manipulated by engineering the antennas' Mie resonances. Spectral overlapping of the dipole-like electric and magnetic Mie resonances results in suppression of backward scattering. This phenomenon is known as Forward Kerker effect which enables the individual nanoantennas to act as Huygens' scatterers. A periodic chain of such Huygens' scatterers may effectively act as a so-called Huygens' metawaveguide with interesting new optical properties compared to non-resonant subwavelength grating waveguide counterparts. Inspiring by these recent findings, in our current research we are investigating more complex integrated photonic components, e.g., micro-ring resonators. In this talk, first I will explain the Forward Kerker effect of the resonant dielectric nanoantennas followed by the functionalities of a straight Huygens' metawaveguide. Next, I will demonstrate our high-Q Huygens' meta-ring-resonators and its different aspects. In conclusion, I will brief on the potential future applications of our demonstrated meta-ring-resonator in nonlinear and quantum integrated photonic systems.
