Harnessing Interfacial Field Localization in Hexagonal GaP Mie Resonators

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
Сharacterization of Mie modes in self‐assembled GaP nanowires grown by MBE in vertical and horizontal configurations. The hexagonal cross‐section suppresses higher‐order modes while preserving dominant low‐order modes with spectral shifts. Simulations and dark‐field spectroscopy confirm the diameter‐dependent tunability.

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

open access: yesNanophotonics, 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 ...

Reciprocal Quantum Electrodynamics With Bound States in the Continuum

open access: yesNanophotonics, 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

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

open access: yesAdvanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...

SHG FROG characterization of

open access: yes, 1998
Accurate phase and amplitude characterization is essential for many ultrashort-pulse applications. Because autocorrelation measurement allows only a rough estimate of pulse duration and does not reveal spectral structure, we adapted the second-harmonic generation frequency-resolved optical gating (SHG FROG) technique to measure 15-nJ fiber compressed ...

Ubiquitous Antiparallel Domains in 2D Hexagonal Boron Nitride Uncovered by Interferometric Nonlinear Optical Imaging

open access: yesAdvanced Materials, Volume 38, Issue 25, 4 May 2026.
Interferometric second‐harmonic generation (SHG) imaging reveals the ubiquitous formation of antiparallel domains in CVD‐grown 2D hexagonal boron nitride. By resolving lattice orientation and SHG phase, hidden domain structures and disorder become visible over large areas. The SHG intensity quantitatively tracks crystalline quality across growth routes,

Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

open access: yesAdvanced Materials, Volume 38, Issue 26, 8 May 2026.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).
