A novel large aperture metalens design strategy achieves broadband achromatic imaging across the visible spectrum (400–680 nm) with a 100° field of view. By incorporating forward mapping optimization and a hybrid algorithm framework, this approach overcomes the limit between aperture size, field of view, and chromatic aberration correction, providing a

Lithography‐free spaced TiO2 NT arrays unlock tunable broadband absorption from THz to UV. By harnessing annealing‐driven phase transitions, strong phonon–polariton resonances emerge in the 1.4–3.6 THz range, whereas high absorptance persists beyond 10 THz.

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 ...

Broadband Electromagnetic Field Prediction at Unseen Wavelengths via Physics‐Guided Neural Operators
A physics‐guided neural operator is trained on electromagnetic field distributions at discrete wavelengths across diverse nanophotonic structures. At inference, given any permittivity map and query wavelength, the model predicts continuous broadband electric‐field distributions with full‐wave accuracy, including wavelengths unseen during training ...
