Rapid progress in the development of metamaterials and metaphotonics allowed bulky optical assemblies to be replaced with thin nanostructured films, often called metasurfaces, opening a broad range of novel and superior applications of flat optics to the
As a two-dimensional planar material with low depth profile, a metasurface can generate non-classical phase distributions for the transmitted and reflected electromagnetic waves at its interface. Thus, it offers more flexibility to control the wave front
To date, however, metasurfaces have used relatively low quality-factor Mie resonances and have an accordingly broad emission spectrum, which restricts the spectral brightness of photons. New research reveals that extended Bound States in the Continuum (BIC) resonances make it possible to harness ...
SANTA BARBARA, Calif., Sept. 24, 2019 — The University of California, Santa Barbara will be the home of the nation’s first Quantum Foundry, a center for developing materials and devices for quantum-information-based technologies. Research at the Quantum Foundry will focus on three main areas...

Nonlinear flat optics devices [1,2,3,4,5,6,7], composed of nanostructured nonlinear materials with a sub-wavelength thickness, were recently showcased as highly versatile, flexible and miniaturized photon pair sources based on spontaneous parametric down-conversion (SPDC). Notably, metasurfaces [8...
