Polarization plays a key role in science; hence its versatile manipulation is crucial. Existing polarization optics, however, can only manipulate polarization in a single transverse plane. Here we demonstrate a new class of polarizers and wave plates—based on metasurfaces—that can impart an arbitra...
holographic image using an ultrathin and single-sized metasurface. This concept opens up distinct dimensions for conventional polarization optics, which allows one to merge the functionality of phase manipulation into an amplitude-manipulation-assisted optical component to form a multifunctional nano-optical...

This review gives a of the methodologies used for the on‐demand dispersion engineering of waves in ...
As a result, the understanding of the BIC-inspired nature of high-Q resonances paves the way towards smart engineering of metasurfaces-on-demand required for various applications of linear and flat optics. Similarly to the case of individual high-Q nanoantennas, the enlargement of Q factor for...

Compared to linear optics, which focuses exclusively on the first term in Eqn 1, nonlinear optics offers a rich and diverse set of nontrivial electromagnetic phenomena. For a monochromatic incident field E = Eω cosωt, the polarization P has nonlinear terms oscillating at various frequencies, ...
These features appear highly attractive for free-space applications including quantum imaging, yet the fundamental potential of photon-pair sources with flat optics for any practical applications remained unexplored in previous studies. Quantum imaging systems based on spatially entangled photon pairs [24,...
Metasurface optics for on-demand polarization transformations along the optical path Article28 January 2021 Introduction Polarization-selective computer-generated holograms (CGHs) are sensitive to the incident polarization and can separate the readout light by its polarization to reconstruct different holographi...
Meanwhile, metasurfaces have shown the high potential of being easily integrated into multifunctional on-chip optoelectronic systems in both optical and radio frequency ranges [14], [15]. The emergence of the so-called flat optics with metasurfaces has yielded groundbreaking phenomena in ...
