Mie Resonances in the Spectrum of Spontaneous Parametric Down-Conversion

We report on the first-time generation of biphotons via spontaneous parametric downconversion driven by Mie-type resonances in subwavelength metasurfaces. The measured biphoton spectrum reveals that emission predominantly occurs at the resonant wavelength of the metasurface.
