Wavelength‐Selective Nonlinear Wavefront Control in Resonant Thin‐Film Lithium Niobate Metasurfaces

open access: yesAdvanced Photonics Research, Volume 7, Issue 10, October 2026.
A LN metasurface converts a Gaussian pump beam into a first‐order Hermite–Gaussian second‐harmonic beam, exploiting spectrally distinct Mie‐type resonances across two nanostructured regions. The resonance‐engineered phase difference enables wavelength‐selective wavefront shaping, active only within a specific spectral window, while leaving the ...

On the Limits of a Space‐Time Description and the Physical Meaning of Phase Space in a Nonlocal Continuum

open access: yesAnnalen der Physik, Volume 538, Issue 10, October 2026.
Nonlocal quantum field theory predicts a finite phase‐space resolution, so even highly squeezed quantum states cannot be localized beyond a fundamental nonlocal limit, providing a potential experimental signature of nonlocality. ABSTRACT In a previous paper we derived an uncertainty relation for nonlocal fields by showing that the physical localization

Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

open access: yesAdvanced Physics Research, Volume 5, Issue 10, October 2026.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...
