One‐Step Fabrication of Non‐Ablative Microstructures for Efficient Second Harmonic Generation on LiNbO3 Thin Film

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This study presents a novel one‐step femtosecond laser modification technique for fabricating high‐quality periodic metasurfaces on lithium niobate thin films without surface damage and scattering centers. Under oblique incidence at 1030 nm, a 4.75‐fold enhancement in second‐harmonic generation efficiency is achieved through complementary mechanisms ...

Polaritonic Spectra of Optical Mie Voids

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Optical Mie voids have been shown to provide a versatile platform for polaritonic physics. Analytical and numerical analysis reveal how void resonances couple to excitonic media, enabling weak‐ and strong‐coupling regimes, polariton gaps, Q‐factor enhancement, and spatial mode localization.

Reciprocal Quantum Electrodynamics With Bound States in the Continuum

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Quantum electrodynamics accurately describes all known forms of modern optics and photonics regarding interactions between photons and matter. In this context, bound states in the continuum with photon confinement in momentum space are envisioned to open an exciting branch called reciprocal quantum electrodynamics. It complements the cavity counterpart

Broadband and Wide‐Angle Nonreciprocal Electromagnetic Transport via Gradient Permeability‐Near‐Zero Metastructures

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
ABSTRACT Breaking time‐reversal symmetry to achieve broadband and wide‐angle nonreciprocity is critical in electromagnetic waves manipulation. While Epsilon‐Near‐Zero materials have revolutionized the control of Transverse Magnetic modes, realizing comparable broadband nonreciprocity for Transverse Electric (TE) modes remains a formidable challenge ...

Terahertz Encryption With a Polarization‐Sensitive Metasurface

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
We propose a dual‐functional terahertz encryption metasurface that enables independent information retrieval in both the near field and the far field within a single device. In the near field, polarization‐selective amplitude modulation reveals textual patterns, whereas in the far field, phase engineering encodes multiple digital data in focal‐spot ...
