Radiation‐Free In‐Gap Finite Barrier Bound States in a Lithium Niobate‐Based Honeycomb Lattice
This work demonstrates radiation‐free finite barrier bound states (FBBSs), successfully overcoming the high propagation loss challenge inherent in conventional FBBS designs while enabling flexible electro‐optic tunability. These findings establish a versatile platform for on‐chip integrated, high‐modulation‐efficiency electro‐optic modulators and ...

Multiple Bound States in the Continuum in Deep‐Subwavelength Nonlocal Polar Dielectric Nanoparticles
Spatial dispersion in polar‐dielectric core–shell nanoparticles enable multiple deep‐subwavelength bound states in the continuum through longitudinal‐transverse hybrid modes. By suppressing radiative damping at finite geometrical parameters, these nonlocality‐induced BICs provide a compact platform for high Q light confinement, enhanced light–matter ...

Full‐Stokes Polarimetry Metasurface‐Enabled Single‐Shot Measurement of the Spin Hall Effect of Light
This study presents a metasurface‐enabled approach to measure the spin Hall effect of light in a single‐shot. The metasurface splits a reflected light into six polarization‐dependent focal spots, allowing all Stokes parameters to be obtained from single image.

Stokes‐Based 3D Polarimetric Analysis of Dipolar Near‐Fields
Characterizing the near‐field polarization of dipolar emitters is of growing importance in nanophotonics, since many subwavelength systems resemble their emission. In this work, we apply the 3D Stokes formalism and its intrinsic reference frame to analyze the polarization properties of various dipole emitters from the near‐ to the far‐field, allowing a

Carrier Funneling and Luminescent Collimation for Extreme Diffuse Light Concentration
Luminescent concentrators show performance millions of times below their thermodynamic limit because of their inefficient design. Carrier funneling combined with luminescent collimation decouples concentration from propagation distance, breaking the practical limitation of current approaches.
