High-angle deflection of metagrating-integrated laser emission for high-contrast microscopy
Integration of curved GaAs metagratings onto VCSELs enables a compact on-chip illumination solution for high-contrast microscopy, making it a versatile choice for light sources in lab-on-a-chip devices.

Unlocking the out-of-plane dimension for photonic bound states in the continuum to achieve maximum optical chirality
We unlock the height as accessible parameter of all-dielectric metasurfaces, allowing polarization-selective interaction of their high-Q eigenstates with light of different helicity and promoting ultra-narrow maximally chiral optical resonances.
